Statistics, a branch of mathematics that is difficult to deal with for every student. And, if you have arrived at this write-up, then no doubt you also might be facing a similar problem. Do you also find reading the graphs of your statistics essay difficult? Is this the reason you are looking to seek statistics essay service? If yes, then don’t skip reading this article. Pondering, why? Because here the professional essay writing service providers have explained how to solve the statistics essay’s problems with a simple trick 68-95-99, also called as Empirical formula. Keep scrolling your screen to know about this.
How to Use Empirical Formula in Statistics Essay:
According to a survey, 95% of statistics for studying students have said that writing statistics essays is a daunting task. Do you also belong to the same category? But, do you know solving them is not as severe as you have perceived. They can easily be solved by empirical formula. To explain to you the same, here is the series of steps. Go through them with maximum attention.
Step 1: Trace the Curve and Divide It
The first step towards solving the graphs of statistics essay through empirical formula is drawing a bell-shaped curve. The highest point of the curve must lie at the top middle, and both the end should be symmetrically sloping both sides, left and right. After drawing it, divide it by creating vertical lines in the following manner:
- Draw a line in the middle. It will divide the curve into two equal parts.
- Draw three lines in each section, i.e., left and right. They should divide both the sections equally into three parts.
Step 2: Give Values to the Lines
Now that you have drawn lines, it’s time to give values to each one of them. Here are the points you must consider before doing it.
- Middle line represents the mean of the statistical data.
- To get the other values of the lines present on the right side, add the standard deviation to the mean.
- To find the mean values of the line available on the left-hand side, subtract the standard deviation from the mean.
Do you need an example to understand it in a better way? Here’s It
Mark the middle line as mean and suppose its value is 15 and keep the value of standard deviation as 3. Now follow the following steps.
- To get the first line’s value of the line on the right hand, add 3 to the mean. You will get 18.
- Repeat the same step for the next two times to get the values of rest 2 lines. You will get 21 and 24 respectively.
- You have to follow the same procedure to get the value of lines present on the left sides of the mean. All you have to do is subtract the standard deviation’s value from the mean value.
- You will get 12, 9, and 6.
Step 3: Assign Percentage for Each Section
Till now, did you get why the empirical formula is called as 68-95-99? Most probably, no. Well, it is called like that because it indicates that 68% of the normal distribution will fall in the standard deviation 1, 95% in deviation 2, and 99% in deviation 3. Mark each of the section to remember them.
Step 4: Calculate the Data Distributions
Now that you have assigned a percentage to each section, it’s time to find data distribution. So, the 4th step will completely deal with solving the statistics essay’s problems using empirical formula. You have to calculate the distributions of the data using the mean. Write them on the curve to keep them in mind.
Step 5: Find the Section to Be Analyzed
Now you’re only one step away from solving statistics essay’s graph problems. After calculating the data distributions, now it’s time to find the section need to be analyzed. Just by applying simple arithmetic rules, this section can now easily be analyzed.
The empirical rule is a gift from the mathematician for the students studying statistics as it has made solving the subject’s problems easy. So, go practice these steps till you don’t become proficient at it and then shock your professor by solving even the toughest statistics essay easily.
