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.
