Question

The following is an incomplete ANOVA table.

Source of Variation	SS		df		MS	F
Between groups			2		11.8
Within groups
Total	100		10

The p-value of the test is

a) less than 0.14

b) between 0.01 and 0.038

c) between 0.025 and 0.18

d) greater tha

Answer 1

Solution:

The completed ANOVA is given as below:

Df within = total df - between df

Between SS = MS between * df between

Within SS = Total SS - Between SS

F = MS between / MS within

The completed ANOVA is given as below:

SV	SS	df	MS	F	P
Between groups	23.6	2	11.8	1.235602	0.340701
Within groups	76.4	8	9.55
Total	100	10

F = 11.8/9.55 = 1.235602

Df1 = 2, df2 = 8

So, P-value by using F-table or excel is given as below:

P-value = 0.3407

Answer: d) greater than 0.10
