Question

Determine the critical value of Scheffe’s test if the given value of the problem is K= 5 and N = 20 with 5% level of significance

Answer 1

Given values are-

$k=5, N=20$

From The table of f-test

The critical value of f-test at 5% is $f_z=2.9899$

Critical value of scheffe's test $=(k-1)\times$ critical value for f test

$=(5-1)\times f_z\\=(4)\times 2.9899\\=11.9596$

Hence critical value is $11.9596$ .
