Scenario: What influences the likelihood of whether a person will assist a stranger? In this study, participants were shown four conditions and asked to provide the percent likelihood that they would be willing to help in each condition. The researcher wanted to see if likelihood of helping varies based on the number of bystanders (0 or 10), and/or the gender of the stranger (male or female). Each participant participated in all four conditions (0 bystanders with a female; 0 bystanders with a male; 10 bystanders with a female; 10 bystanders with a male). Question: If p = .035 for the main effect of number of bystanders, what should the researcher conclude?
