However, using it, you can not differentiate between someone who got 81 and someone who got 95 (as both would get the A grade). Now there is nothing wrong in this kind of grading system.

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 youвЂ™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, letвЂ™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 вЂ“ вЂњYou will be graded on the curve?вЂќ). In the bell curve, the highest point is the one that has the highest probability of occurring, and the probability of occurrencesВ 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.
