Population mean = µ = sum of data values / total number of observations = µ = \ ( \frac {\left (2\:+\:8\:+\:11\:+\:14\:+\:20\right)} {5}\) = µ = \ (\frac {55} {5}=11\) Step 2: Now subtract the data values from the mean and find the square of differences. Step 3: Find the statistical sum of squares.
Webbtailed or two-tailed test. The one-tailed version tests in only one direction, i.e. variance of the first population is either greater or less than the second population but not both ways. The two-tailed version tests for the hypothesis that the variances are not equal but one can be greater or less than the other. Webb23 mars 2024 · Introduction.
