Use Excel’s ToolPak to compute Two-Way ANOVA and submit your statistical output.

1. Are there any significant main effects or an interaction effect?
2. Interpret your answer.

Answer 1

from excel: data -data analysis:two way ANOVA( with replication)

statistical output is:

Source of Variation	SS	df	MS	F	P-value
stage	30	1	30.00	4.04	0.0557
Groups	740	2	370.00	49.89	0.0000
Interaction	260	2	130.00	17.53	0.0000
Within	178	24	7.42
Total	1208	29

since p value for Groups is less than 0.05 ; there is a significant main effect for groups

and p value for interaction is less than 0.05 ; there is a significant interaction effect.
