Nerdy Bot Scholarship Essay by Dora M. Donnelly

Our Nerdify reviews team believes that video blogging is the modern type of journalism that helps to unite people from all over the world. Regardless if you would like to tell the world or the local community about some environmental issues or share cooking tips for the college students (or those who just want to taste something delicious!), video blogging is the way to go. Moreover, as we are fighting the post-effect of social distancing and the times of uncertainty, one should think about becoming a video blogger because it will help us to stay in touch with family and friends as we share our lives and skills online.

1. You Can Become a Successful Influencer. According to our experts at Nerdify reviews, no influencer that has started a video blog would get by without being the promoter with an active social position. While it may look like just walking around with a camera, there are many secrets that are involved as the person promotes various locations, local cafes, restaurants, even books and movies as the objects are getting into the frame. Think of what you would like to promote, contact the companies that you know well, and make it your business as you influence people!

2. Video Blogging Helps to Make Friends Around The World. The best part, according to our staff at Nerdify reviews, is to make friends and discover various cultures and traditions as your video blogging activity can take you anywhere. You shall receive comments and questions from people somewhere in Japan or Brazil, which will help you to learn and become more socially active. The trick is to stay friendly and show respect as you tell people about your country or share your skills with the rest of the world. Remember to provide explanations and study your target audience!

3. You Can Participate in International Volunteering Projects. Do not forget that you can also promote important social events by becoming a volunteer. You can also highlight the events and important social processes in your local community. It may be anything from environmental issues to the construction of the roads that have been promised by the local officials, yet there are still dangerous spots where the children play. As we know, the help of video bloggers cannot be underestimated as they become the voices of freedom and awareness!

4. You Can Promote Your Ideas & Hobbies. If you are an athlete or a musician, you can use video blogging as a safe way to promote your ideas and skills. If you know how to dance or would like to provide free or paid singing lessons, video blogging becomes great assistance for your promotion. The most important is to provide something truly unique! The trick is to keep your video blogging active, which will make your content recognizable. Think about how to design your intro and the ending credits and keep track of your statistics as you do so!

5. Video Blogging Improves Your Social Skills. It is not often mentioned but many of us (even those who did not get famous yet) have improved our social skills. You will learn how to form your sentences and express your ideas. If you are majoring in Journalism or Political Science, starting a video blog will be quite helpful as you will think over your ideas and will position your beliefs correctly. Always show respect and try to avoid any sensitive topics that may hurt or offend people by accident. As your videos might reach a global audience, consider this aspect as you get creative!

6. You Can Work In The Field of Marketing. Finally, you can work in the field of SMM (Social Media Marketing) by becoming a video blogger who can provide examples of various promotion methods. It can be anything from your private tutoring sessions in the field or promotion for the large companies as your name becomes recognizable.

We’ve got a feedback story from our grateful customer who decided to share his success story and help students who struggle with the chi-squared test.

This article contains a full and really simple guide to solving chi-square. To keep his identity anonymous, we’ve changed his name.

I’m Donald and this is my story about conquering chi-square. Einstein was completely right saying that, “If you can’t explain it to a six-year-old, you don’t understand it yourself.”

If you’re currently struggling with the chi-square test, I’ll answer all — and I mean all — your questions about this tricky statistical method in really easy to understand terms!

I’ve adapted this article from the “Methodology” section of my paper. You are welcome to use it to understand how the methodology of your own homework should work.

What is the Chi-Square Test and Where to Use It?

The first time I had to use chi-square was when I was at the 4th year of my undergraduate program at Pittsburgh University School of Nursing. I planned to prove that googling about mental health issues can cause anxiety and negative emotions.

Thus, the topic of my paper was “How reading of online resources about mental health issues impacts patients’ mental and emotional state”.

I surveyed 100 patients. I asked them how often they read about health issues, and whether such a guilty pleasure triggers their anxiety. Then, I recorded their answers on a table.  

All I needed was to find the right statistical test. I looked through a short chi-square guide online and it totally triggered my math anxiety.

You know, I felt that I’m the dumbest person in the world. Thankfully, I did not give up and continued.

❓ What is the Chi-Square Test?

First things first, I got to know my enemy. Chi-square test is a common statistical method used to determine whether two things (in statistics they are called variables) are somehow related.

❓ How to find out whether variables are related? If one variable somehow changes, and another immediately changes in response, it means that they are related.

This is actually very simple to understand once you put the concept of chi-square in the context of a real example.

In my case, patients would be reading about health issues online and experience anxiety. If they feel bad after browsing horrifying symptoms of mental illnesses on WedMD, that means these variables are related.

To make sure that the chi-square method suits your particular research, check these criteria:

1. You need to analyze numerical results — specifically, the numbers of times you’ve observed something happening, or how many people gave the same response.
2. Variables are categorical — variables should belong to specific groups. For instance, respondents in surveys can be categorized by gender, age, political views, etc.
3. There are two individual variables (e.g. how frequently people google online about mental illnesses (very frequently or rarely) and the effect of their googling (increased anxiety or no negative emotions)
4. You only need a “yes” or “no” answer – chi-square can only tell if two variables influence each other. It never tells how strong the influence is and when or why it occurs.

Chi-square is used pretty much anywhere because it is a simple, suitable for any sample size, and cheap way to test whether two variables are related. For instance:

 

• In healthcare: is anxiety associated with online research about health issues?
• In sociology: is crime rate related to the poverty level in a specific region?
• In marketing: do sales depend on the region where products are sold?
• In politics: does voter turnout depend on voter age?

Given all this info, I decided that chi-square was exactly what I needed for my research. But how to convert my data into a table and then get all the calculations done right? After 5 days of trial and error, all I had was only errors and I got stuck.

Why Chi-Square Test is Mistakenly Thought to be Difficult?

You’d think that the good old Google knows everything, but nope. Page after page of the search results, I saw the same explanations by-the-book, which were all Greek to me. Without statistical education, I got the theoretical part but was completely lost when it came to practice.

Then a friend of mine recommended me Nerdify. Nerdify connected me with a perfect Nerd — a Master in Medical Statistics and finally, I knew I was going somewhere!

A detailed explanation from the Nerd on how chi-square works and how I should use it — it was all that I needed to nail my super difficult paper.

Why was chi-square so difficult for me? As my Nerd said, it happens with all the students for the following reasons:

• Extremely complex definitions and explanations that make chi-square seem very entangled and confuse students
• Without illustrative examples, complex formulas are overwhelming for anyone who does not have a fancy for math.
• Lack of time teachers can devote to explaining every topic — students often have no one to ask for an extra explanation
• Lack of knowledge due to that your major doesn’t have anything to do with statistics. As a student nurse, I didn’t have any background in studying statistics at all.

If you’re struggling just as I did, for whatever reason, I’ve got a perfect step-by-step guide to chi-square that you can use!

Really Simple Step-by-Step Chi-Square Guide

Right off the bat, you should know that it’s totally acceptable for non-statistics students to skip doing all the calculations manually and use online chi-square test calculators.

However, my college professor required all the chi-square formulas explained in the paper. Thus, if you’ll use chi-square, you need to understand this method to interpret the results correctly.

▶ Formula Explained

When you see this abomination of a formula, you probably think it’s extremely complex:

where

• χ2 — value of chi square
• Σ — sign of sum, means the total amount of elements in a sequence
• O — observed value of a variable, or the numbers you already have from observations or task description
• E — expected value of variables you need to calculate yourself; they represent how the variables would be distributed if there would be NO relationship between the variables

Even if you do all the calculations using MS Excel or SPSS, you still need to know where to put which number!

In sections below, you fill find out more about where to find these numbers.

Now it’s time for the best part — calculations!

 

0️⃣ My Case ➕ Sample Size

In my research, I surveyed 100 patients. I asked them how often they read about health issues, and whether such a guilty pleasure triggers their anxiety

• So there were two categories of patients: those who frequently research health issues and those who rarely research them
• There were also two options of their emotional response: increased anxiety and no changes  

Right now, I know my sample size — the number of observations. How many people responded to the survey? How many times you’ve seen something happening during the experiment or study?

In my case, sample equaled 100 — the number of people who participated in the survey.

 

1️⃣ Creating a Chi-Square Table

Using this data, I created this contingency table:

❓ Contingency tables present observations in matrix format — rows and columns, just like the table above. This type of tables is very commonly used in statistics, especially because it demonstrates how two variables are connected.

---

	Increased anxiety	No changes	Total
Frequently research
Rarely research
Total

---

 

2️⃣ Choosing Statistical Significance

If you’re writing a paper using the chi-square method, chances are that the level of statistical significance isn’t given. Where do you get it? You choose it yourself!

❓ Statistical significance — is the likelihood of that the relationship between two or more variables is accidental and the results of the observation are caused by something else than just chance.

For instance, if a patient gets anxiety every time he does online research about health issues, then statistically the probability of getting anxiety, aka level of confidence is 100%, or 1.

If a patient gets anxiety in 9 times out of 10, then we can confidently state that the probability here is 90%, or 0.9.

The most typical levels of significance are 0.05 and 0.01 — both are 100% safe to use in your paper. I chose 0.01 because the lower the value, the more significant results you’ll get — lower significance implies a lower risk of error.

Why do we need the level of significance? My Nerd had a good metaphor to explain it. Imagine that you have to climb up a ladder that has 100 steps. The more steps are missing, the higher the risk that you’ll fall. That’s why we set a very low level of significance — to make sure that calculations are correct!

 

3️⃣ State your Hypotheses

The hypothesis is a fancy word that confuses many students, but in reality, the hypothesis is just an assumption that you have. In chi-square, you’ll need 2 of them.

• Null hypothesis (H0)– usually states that the results of the observations could result purely from chance and the variables are independent — if one of them changes, another one stays the same and doesn’t react to the changes in the first one.

My H0 would say that getting anxiety isn’t connected with researching health issues online.

• Alternative hypothesis (H1)  states that the sample observations result not from a random cause, but from a specific cause and the variables are dependent in some way.

That is, my H1 says that patients really do get anxiety and experience negative feelings after researching health issues online.

4️⃣ Fill in Observed Values

Here just enter all the observed values into the table:

❓ Observed value — what actually happened or how many times you’ve seen something occur. For instance, how many respondents out of 100 admitted to frequently research online about mental issues and get anxiety from it

---

	Increased anxiety	No change	Total
Frequently research	36	9	45
Rarely research	24	31	55
Total	60	40	100

---

5️⃣ Calculate Expected Value

Here we calculate values that would be observed in case if there would be no relationship between researching health issues and experiencing negative emotions.

❓ Expected value — it’s calculated by the formula below and show what would happen if the variables were absolutely independent — wouldn’t affect each other at all.

where

• E — expected value
• Mr — row total for the cell you’re calculating an expected value for
• Mc — column total for that cell
• n — sample size
  

  ---

	Increased anxiety	No change	Total
Frequently research	27	18	45
Rarely research	33	22	55
Total	60	40	100

---

• Expected value for “frequently research, increased anxiety” E=45*60/100=27
• Expected value for “only rarely research, increased anxiety” E=55*60/100=33
• Expected value for “frequently research, no negative emotions” E=45*40/100=18
• Expected value for“only rarely research, no negative emotions” E=55*40/100=22

 

6️⃣ Calculate Chi-Square Using the Formula

Once again, you can use online calculators, but this how it’s done in practice (aka the hard way):

7️⃣ Calculate Degrees of Freedom and Critical Value

Now that we got chi-square calculation done, let’s calculate the degrees of freedom

❓ Degrees of freedom (df) — the number of independent variables that went into the calculation.

Just think of those promotions “buy 2 — get 1 for free!” — you’re free to choose several things, but +1 product is always set by the promotion. Degrees of freedom, however, subtract 1 from both your rows and columns.

You need to use a chi-square distribution table and find your critical value at the intersection of the degrees of freedom (df=1) and the level of significance (α=0.01):

So, our critical value is 6.63. This value is smaller than our χ2 =13.63 Therefore, in our chi-square test example, researching about health issues online and getting anxiety or negative emotions are related.

We don’t know how much they are related, because chi-square doesn’t answer this question. But we definitely know that they are somehow related.👌

Chi-Square Calculators — the Easy Way

Even if you need to do all the difficult calculations by yourself, these calculators are awesome to verify your results. Or, if you’re lucky, online calculators are all you’ll need to use to calculate chi-square!

1. Social Science Statistics Calculator — easy to use chi-square calculator that can calculate up to 5 rows and 5 columns. You can enter category names, fill in the data, and get the result in a flash.
2. Kent University SPSS Guide for Chi-Square — if you have SPSS, you can consider your chi-square test pretty much already done. This guide will help you learn how to import chi-square tables and graphs into the SPSS and get the task solved. Many colleges and universities use SPSS as their default tool, and your professor may ask you to show your SPSS datasheet.
3. Chi-Square Calculator — another extremely simple online chi-squared test calculator. All you need to do is enter the observed values and you’ll get degrees of freedom and chi-square ready.

How Can You Nail Chi-Square: My Pro Tips

If anyone told me I would be able to do it just a week before connecting with a Nerd, I’d never believed it. It was simple and logical explanations from my Nerd that helped me completely nail chi-square test and do all the calculations by myself.

Now, I understand each step of chi-square and interpret results correctly. For me, it was crucial that a professional, with a background in studying and applying statistics in practice, would explain everything to me in human language, not math language.

And now a few tips for you to cut corners if you’re dealing with chi-square:

• Keep in mind that chi-square isn’t rocket science — it is doable and actually very easy if you have a really simple and detailed guideline
• The number of rows and columns can vary and your table can be much larger than mine, however, the principle remains the same — you’ll just need to do more arithmetic
• When calculating the expected value, you’ll most likely get fractions, which can confuse you, especially if you’re calculating the number of people in each category. Don’t bother about it — these calculations are intended for further calculation of chi-square

That’s all I wanted to share in my feedback story today. Hopefully, it will help you nail chi-square and get the grade you deserve! Chi-square isn’t as difficult as it may seem at first, so go ahead and break a lance!

One of the biggest challenges we face every day is getting out of bed and starting our day. Most people have trouble getting out of bed in the morning, but it can be even harder for college students who attempt all-nighters half the time.

It can be tough to muster up the energy to face the day, but the Nerdify Reviews team found a few things you can do to help make it a little easier.

The Challenge of Getting Out of Bed

The challenge of getting out of bed in the morning for college students is real, but it’s worth it. It can be hard knowing that night before was spent up all night studying or hanging out with friends, but it’s important to muster up the energy to get up anyways.

College life can be exhausting, but it can also be really fun. It’s the one time in your life when you can get away with not holding a full-time job. It’s the one time when you can dive into your passions, hobbies, relationships, and studies. It’s important to have your whole day available so that you can experience college life to the fullest.

Waking up Motivated in the Mornings

Waking up motivated can be hard for anyone, but especially college students. Waking up early is one thing, but waking up motivated to start your day off right is a whole other story. It can be helpful to try to stick to a solid routine, establish a set goal for the day, and make sure to get plenty of sleep. If you can follow the morning motivation tips listed below, you’ll be well on your way to having a productive and successful day!

Establishing a good routine is the best way to combat daily motivation struggles. Creating a system that allows your brain to anticipate what is coming and what to expect is important for having motivated mornings. Although having a routine is not specifically related to waking up early, it is definitely a factor that can help.

Nerdify Reviews Top 7 Proven Ways to Get Out of Bed Faster

1. Get plenty of sleep

This is probably the most important thing you can do to have a motivating morning. The National Sleep Foundation recommends that adults aged 18-64 get 7-9 hours of sleep per night.

2. Establish a good routine

As mentioned before, having a routine helps your brain anticipate what is coming and makes it easier to stay motivated. It will keep your circadian rhythm on track and prevent you from waking up too late. A good routine will keep you getting in bed early so you can wake up feeling refreshed

3. Set realistic goals for the day

Don’t try to aim too high or else you’ll quickly become overwhelmed and discouraged. Start off with one or two attainable goals and work your way up from there. You don’t need to be an entrepreneur who wakes up at 4 am with morning motivation affirmations. Just be yourself and have realistic goals of getting up early while still getting enough sleep.

4. Make sure your environment is conducive to productivity

This means having a clean and organized space as well as avoiding distractions like social media and television can be great morning motivators. Making your bed can also be a good start to your day once you get up early.

5. Drink plenty of water throughout the day

Dehydration can often be mistaken for fatigue, so make sure to drink plenty of water to stay energized and be motivated in the mornings. Nerdify Reviews experts recommend keeping a glass of water on your nightstand for extra hydration.

6. Exercise mentally & physically

Take breaks throughout the day to move your body and get some fresh air. Sitting in one spot all day is not good for your health or productivity, so make sure to get up and move around every once in a while.

7. Reward yourself

Reward yourself for completing tasks throughout the day! Giving yourself a small incentive (like allowing yourself an extra hour of sleep) can be a great way to find your morning motivators.

Implementing Morning Motivators Into Your Daily Routine

If you want to start your day motivated, there are a few things you can do to help make it easier. One of the best things in morning motivators is to set some goals for yourself for the day. When you have something to work towards, it’s a lot easier to get out of bed and get started. You can also try drinking a glass of water as soon as you wake up. Not only will it help refresh you, but it’ll also help kickstart your metabolism for the day.

Another great way to be motivated in the mornings is to take some time for yourself when you wake up. Whether that means reading, morning motivation affirmations, meditation, or spending time in nature, taking a little time for yourself can help set the tone for the rest of your day. And lastly, try to make your morning routine as enjoyable as possible. Whether that means listening to your favorite music or reading your favorite blog, doing things you enjoy can help make getting up easier.

With these morning motivators in mind, you can start implementing them into your daily routine and start your day off on the right foot.

In Conclusion

Waking up motivated in the morning is no easy task, but it is possible with the right mindset and strategies. By getting enough rest, setting realistic goals for yourself, making sure your environment is conducive to productivity, drinking plenty of water throughout the day, exercising mentally & physically, and rewarding yourself for completing tasks — you can start enjoying a productive and energized day!
