Question
A consumer researcher was interested in what factors influence people’s fear responses to horror films. She measured gender (0 = female, 1 = male) and how much a person is prone to believe in things that are not real (fantasy proneness) on a scale from 0 to 4 (0 = not at all fantasy-prone, 4 = very fantasy-prone). Fear responses were measured on a scale from 0 (not at all scared) to 15 (the most scared I have ever felt). How much variance (as a percentage) in fear is shared by gender and fantasy proneness in the population? Give a percentage as a response without the % symbol (e.g. 10.1). Use only one decimal.
Solution
Since you are asked to provide the percentage of explained variance in the population, the correct answer is the Adjusted R2 and not the R2.
