Question

Conduct an ANOVA test, assuming equality of variance, and complete the ANOVA table below the data set.

Determine if there is a significant F-ratio among the three samples from the P-value indicator (round to two decimals).

Calculate the omega-squared value.

1) Using the data set from your data sheet for height, complete the ANOVA table below. Determine if there is a significant F-Ratio among the three samples from the P-Value indicator (round to two decimals).   Calculate the Omega-Squared Value.

Height A	Height B	Height C
64	63	53
66	68	71
69	75	78
63	68	69
68	65	77
62	64	68
63	78	62
60	71	69
66	68	55
66	66	67

Answer 1

Following is the outut of one way ANOVA:

Anova: Single Factor
SUMMARY
Groups	Count	Sum	Average	Variance
Height A	10	647	64.7	7.788889
Height B	10	686	68.6	23.15556
Height C	10	669	66.9	67.87778

Source of Variation	SS	df	MS	F	P-value	F crit
Between Groups	76.46667	2	38.23333	1.16067	0.32842	3.354131
Within Groups	889.4	27	32.94074
Total	965.8667	29

The F test statistics:

F = 1.16

The p-value is: 0.3284

Since p-value is large so F ratio is not significant.

The omega square is:
