The bell-shaped curve is the best fit to gauge the employee, rate them, and then reward them accordingly to make the comparison fair.Īll the higher-rating employees in the bell curve will be placed on the right-hand side of the bell curve, low-rating employees will be placed on the left-hand side of the bell curve, and average employees will be placed in the center of the bell curve. For example, if you got 8 as a rating and your team member got 7 as the rating, there would not be much difference here. Then, only a few employees get a higher rating, a majority will get an average rating, and a few will get a low rating. Plating a bell-shaped graph shows the highest probability of the outcome, and the likelihood of the outcome keeps going down when the bell shapes move to either side from the center point.įor example, look at the below Excel bell shaped curve graph.Īssume you are working in a team of 50 members, and your rating is very similar to the other team members.
They gauge employees on low or non-performers, average performers, and high performers. Using this performance appraisal, they reward employees in terms of salary, promotions, etc. All the organizations work on performance appraisal for a specific period frame.
read more is the graph commonly used to gauge the performance appraisal of company employees. It gets its name from the shape of the graph which resembles to a bell. The bell curve Bell Curve Bell Curve graph portrays a normal distribution which is a type of continuous probability. We can plot the standard deviation in the Excel graph called the “ bell-shaped curve.” Typically, the standard deviation is the variation on either side of the average or means value of the data series values. For example, in the stock market, how the stock price is volatile. The standard deviation is one of the important statistical tools which shows how the data is spread out. The standard deviation graph is also known as the bell curve graph in Excel. The other is negative to the mean, shown on the left-hand side of the graph. There are two deviations represented in the standard deviation graph, one positive to the mean, shown on the right-hand side of the graph. We know that standard deviation is a calculation of how the values are changing with comparison or the respect to the mean or the average value.
