Concept Introduction:
Comparison of Standard Deviation with F Test:
For the comparison of mean values of two sets of measurements, we decide whether the standard deviations of the two sets are “statistically different”. This is done by F test.
The F test with quotient F is given as:
Where,
If
Degrees of Freedom:
For a n set of measurement, the degrees of freedom will be
Comparing replicate measurements:
