A researcher conducted a study on the effects of stress on migraines. The researcher computed the number of migraines individuals reported during a six-month time frame as a function of the amount of stress they reported during that same time period. There were three stress levels: low, mild, and severe. The sums of squares appear in the following ANOVA table. The means for each condition and the number of participants per condition are also provided.

Source	df	SS	MS	F
Between groups		22.167
Within groups		14.750		---------
Total		36.917	---------	----------

Stress Level	Mean	N
Low	3	4
Mild	4	4
Severe	6	4
