Probstat/week15 practice 1

Generate 5 sets of samples from normal populations, each of size 10, on a spreadsheet software. Make sure that the mean and variance of each set can be modified easily.

Then compute

$SS_{w}=\sum _{i=1}^{m}\sum _{j=1}^{n}(X_{ij}-{\bar {X}}_{i\cdot })^{2}$

and

$SS_{b}=n\sum _{i=1}^{m}({\bar {X}}_{i\cdot }-{\bar {X}}_{\cdot \cdot })^{2}$
