Scenario: A therapist wanted to examine marital happiness in couples participating in therapy at her clinic. Couples were randomly assigned to participate in individual, couples, or group therapy. She measured marital happiness using a standardized scale ranging from 0 100, with higher numbers indicating greater marital bliss. She measured marital happiness at three time points from the start of therapy sessions (1, 6, and 12 weeks) and compared those across the three types of therapies offered. Question: If p = .071 for the main effect of time, what should the researcher conclude?
