WebFind standard deviation of the given population data: 10, 12, 18, 14, 21, 27 Solution Step 1: Calculate the expected value of population data: N = 6 Step 2: Calculate (x i - µ) by subtracting the mean value from each value of the data set and calculate the square of differences to make them positive. WebWhen there are only two groups the test we use to determine if the variance is the same is called a variance ratio test. The test involves dividing the variance of group one by the variance of group two. If this ratio is close to one the conclusion drawn is that the variance of each group is the same.
