Measures Of Dispersion For Ungrouped Data In Frequency Table Variance Method 1 Youtube None of the above answers is correct. . Class Intervals Frequency f Midpoint x f x. Lets look at how to determine the Standard Deviation of grouped and ungrouped data as well as the random variables Standard Deviation. The data set is a population c. You will be going to get a number of data set from value 1 through the value N so for calculating the value of variance for given data set you will be going to select a cell that is empty in an excel spreadsheet. The variance of a data set is the average square distance between the mean value and each data. When data is expressed in the form of class intervals it is known as grouped data. A small variance obtained using the sample variance formula indicates that the data points are close to the
