PSY 520 SPSS Assignment 1 Before you begin the assignment: • Read Chapter 8 in your Discovering Statistics Using IBM SPSS Statistics textbook. • Review the video tutorial for an overview of conducting multiple regression in SPSS. • Download and open the Popularity SPSS data set. An overview of the data set: This data set represents hypothetical data from a study that examined how well some core personality traits predict a person’s level of popularity. Personality was measured using the “Big 5,” which is a very commonly used measure of personality. In fact, a Big 5 personality scale was included in the Module Two discussion. Here is some more information about the variables in this hypothetical data set: • Number: This is the ID number of the participant • Sex: Participants’ sex, with “1” standing for male and “2” standing for female • Age: College year of the participant, with “1” standing for freshman, “2” standing for sophomore, etc. • Popularity: Popularity measured with a questionnaire that could range from 0 to 100, with higher numbers indicating more popularity • Extroversion: A Big 5 trait indicating level of sociability. Scores range from 1 to 5, with high numbers indicating extroverted and low numbers indicating introverted • Agreeableness: A Big 5 trait indicating level of interpersonal warmth and friendliness. Scores range from 1 to 5, with high numbers indicating warmth and low numbers indicating coldness towards others • Conscientiousness: A Big 5 trait indicating level of self-control and responsibility. Scores range from 1 to 5, with high numbers indicating high conscientiousness and low numbers indicating low conscientiousness • Neuroticism: A Big 5 trait indicating level of anxiety and emotional stability. Scores range from 1 to 5, with high numbers indicating high neuroticism and low numbers indicating low neuroticism • Openness: A Big 5 trait indicating level of willingness to try new things and creativity. Scores range from 1 to 5, with high numbers indicating high open-mindedness and low numbers indicating closed-mindedness Questions: 1) Describe in your own words what type of research situations call for a researcher to use a multiple regression analysis.
