Question

7. Fill in the missing values:

Source	SS	df	MS	F	Crit.
Total	94
Between		2
Within	63		3

Answer 1

Using above table we get,

Between SS = Total SS - Within SS = 94 - 63 = 31

Within DF = Within SS / Within MS = 63/3 = 21

Total DF = Between DF + Within DF = 2 + 21 = 23

Between MS = Between SS / Between DF = 31/2 = 15.5

F = Between MS / Within MS = 15.5/3 = 5.17

since, we don't know significance level we assume it to be 0.05. That is,

F-critical value at with DF1 = 2 and DF2 = 21 is,

F_crit = 3.467

Hence, we get, folliwing table,

Source	SS	df	MS	F	Crit.
Total	94	23
Between	31	2	15.5	5.17	3.467
Within	63	21	3
