Multiple Regression lab 12 psyc 274 Lab 12 - The dataset contained in the "lab12assn.sav" file consists of real data from a published study (Ong et al., 2011) looking at the relationship between narcissism and behavior on Facebook in high school students. There are 5 variables: Age, Gender, Extraversion, Narcissism, and Rating. Age is measured in years, gender is coded as 0 for females, 1 for males, and extraversion and narcissism scores come from scales measuring each of these constructs. These 4 variables will be the predictors, while Rating will be the outcome. Participants were asked to rate their own Facebook profile picture on 4 dimensions: coolness, glamour, fashionableness, and attractiveness. Rating is taken to be the sum of these ratings, indicating how positively they perceived their profile picture
