You can do this quickly by using the autofill option, or use the fill handle and drag it down to fill the cells.

In the cell below it enter 36 and create a series from 35 to 95 (where 95 is Mean + 3* Standard Deviation).This value can be calculated using Mean – 3* Standard Deviation (65-3*10). Here are the steps to create a bell curve for this dataset: (You can calculate the mean using the AVERAGE function in Excel and Standard Deviation using the STDEV.P function). The mean score of the class is 65 and the standard deviation is 10. Let’s take an example of a class of students that have been scored in an exam.

Now let’s see how to create a bell curve in Excel.

But since you set a really easy paper, everyone scored above 80 and got the A grade. According to your grading system, anyone who gets above 80 out of 100 gets an A grade. Suppose you have a class of 100 students that appear for an exam. This means that even if your team is the best team ever and you’re all superheroes, only a handful of you would get the top rating, most of the people in your team would get an average rating, and a handful will get the lowest rating. Suppose you work in a team of 100 members and your manager tells you that your performance will be relative to others and will be evaluated on the bell curve. Now before I jump in on how to create a bell curve in Excel, let’s get a better understanding of the concept by taking an example. It is often used during employee performance appraisals or during evaluation in exams ( ever heard – “You will be graded on the curve?”). In the bell curve, the highest point is the one that has the highest probability of occurring, and the probability of occurrences goes down on either side of the curve.

A bell curve (also known as normal distribution curve) is a way to plot and analyze data that looks like a bell curve.
