WebWhen you have raw data points, first you need to find the standard deviation and sample mean of the data. The formulas for standard deviation & population mean are: S.D = √⅀ (Xi -µ)2/N-1. Where, Xi is each value in the data set. µ is the mean of all values in the data set. N is the total number of values in the data set. WebThe mean is the average of the observations in the data set. To calculate the mean, we add up all the observations and divide by the total number of observations. For male subjects, the sum of all observations is 113, and there are 20 observations. Therefore, the mean is 113/20 = 5.65 (rounded to the nearest hundredth). how to use game pass code on pc
