Question

14. A. please!!

15) (6) Among other benefits, pets are thought to be great companions that increase life satisfaction among pet owners, especially those who would otherwise live alone. A psychologist decides to test this notion. Subjects who live with others or who live alone (Factor A: living status) and own pets or do not (Factor B: pet owner status) were asked to indicate how satisfied they were with their living arrangements. It was expected that (x) pet owners would report greater overall satisfaction than those who did not have pets and that (y) this benefit would be stronger among those who live alone. Hypothetical data from a study like this appear below (higher scores indicate greater life satisfaction): no Factor B: pet owner yes M = 9.0 M = 6.0 M = 8.0 M = 3.0 Factor A: living status lives alone does not live alone a (3) Which expectation (choose one: x or y) corresponds to a main effect? In addition to choosing i or ii, say whether it appears that this expectation has been met AND say how you know this.

Answer 1

a)

X corresponds to the main effect.Because we are actually looking first whther pets increase the satisfaction or not

Expectation seems to be met because Pet owner(Yes) vs Pet owner(No) shows that M is always high for Yes irrespective of living status.

Please let me know in case of any doubt.

Thanks in advance!
