Standard deviation is another important population parameter to be
|
|
|
tested.
|
|
|
q |
We want to know if the standard deviation estimated from two samples
|
|
are significantly different.
|
|
|
q |
The statistical test used to compare the variability of two samples
is the
|
|
F-test:
|
|
|
S12:
the estimate of the population variance of sample 1
|
|
|
S22:
the estimate of the population variance of sample 2.
