Suppose you are trying to show that there is a relationship between gender, living arrangement and the number of texts sent daily among students.

Prompt: Suppose you are trying to show that there is a relationship between gender, living arrangement and the number of texts sent daily among students. You take a sample of 12 students, record their gender (F&M) and ask whether they live at home (H), campus (C), or off campus (O)

	H	C	O
F	3 & 7	9 & 13	12 & 16
M	1& 5	3 & 7	2 & 6

Questions: (Known top row effect = +3, sum of square total =244)

1. What is the sum of squares interaction? (correct answer is 32)

2. What is the mean square for the row variable? (correct answer is 108)

Solutions

Expert Solution

Hence

SS interaction = SS r*c = 32

MS for row = 108
