While reviewing staffing plans for a new pilot plant, Colin Chenaux, VP of Operations at Clovis Chemicals, Inc., designed an experiment to test the effects of "supervisor's style" and "training method" on the productivity of operators. The treatment levels were: (1) authoritarian, and participatory for supervisor's style, and (2) technical manuals, training films, and multimedia for training method. Three of qualified applicants were randomly selected and assigned to each of the six cells. Analysis of Colin's data produced the following ANOVA table.

Source of Variation	SS	df	MS	F
Rows (supervisor's style)	410.8889
Column (training method)	120.7778
Interaction	2.111111
Within	109.3333
Total	643.1111	17

Are there interactions?

Which one of the factors (attributes) contributes more to understanding overall variation in productivity?

Would you need to do multiple comparisons for supervisory style as well as for training method to understand which method works the best in improving productivity?
