Example 1: Calculate the mean and variance of the sample data from the frequency table in Figure 1. Figure 2 â Calculation of mean and standard deviation from frequency table. The required calculation is displayed in Figure 2.Here cell F11 contains the formula =D11/E11, which calculates the mean, and cell G14 contains the formula =(D14-E14*F14)/(E14-1), which calculates the variance.n this case the midpoint of each interval is assigned the value xi. Example 2: Calculate the mean and variance for the data in the frequency table in Figure 4. Figure 4 â Calculations for a frequency table with intervals. x x â¤ 10, etc.
