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:

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.

 

Type answer below:

 

 

 

2a) Run a basic correlation of matrix for the Popularity, Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness variables.

 

Paste output below (Read carefully: The best way to do this is to select “Copy Special” when copying from the SPSS output. Then select image as a format to copy. When pasting in Word, select Paste Special, choose a picture format, and then resize the image so it fits the screen):

 

 

 

2b) Based on these results, which personality variables are significantly correlated with Popularity?

 

Type answer below:

 

 

 

3a) Conduct a multiple regression analysis using Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness as predictors of Popularity.

 

Paste the output below:

 

 

 

3b) Which variables are significant predictors of Popularity? Compare and contrast the results from the multiple regression analysis to the basic correlation results from question 2b.

 

Type your answer below:

 

 

 

3c) What is the R-squared of this model, and what does it tell us about how well this model predicts Popularity?

 

Type your answer below:

Unit 5: Unit 5: Lifestyles and Health – Discussion

Throughout this course, many opportunities are available to post an initial response to a Discussion topic as well as to respond to your classmate’s responses.

After you have completed the Reading, and without reviewing your classmate’s responses, post your initial response to the following discussion. Your post should be at least 300-350 words in length and should extend the discussion of the group supported by your course materials and/or other appropriate resources.

Read the scenario and answer the following questions:

Eating Scenario

When 15-year-old Melanie went through puberty, she experienced and increase in appetite and gained about 20 lbs. Her family laughingly referred to her as “chubby,” not realizing how deeply she was affected by their teasing. Melanie began using diet pills she ordered out of the back of a magazine and greatly restricting her food intake. She lost the 20 lbs. very quickly, and she received many compliments about how good she looked. Melanie lost another 15 lbs. on top of that, and when she received comments about looking too thin, she began to wear baggy clothing to hide her frail figure. Her daily food intake by this point was restricted to one small bag of pretzels, one apple, and one small container of yogurt. Melanie would exercise for up to 2 hours per day to burn off the calories from the food she had consumed. She found the diet pills were causing her to feel sleepless and irritable, however she was afraid to stop taking them for fear of regaining the weight she had lost. She ended up increasing the dose. Finally Melanie’s parents, concerned about her appearance, sought help for her.

Why is a balanced diet important to a healthy body and mind? What health problems can result when a person eats/exercises too much, or too little? Is Melanie suffering from an eating disorder? Using the disease model of addiction as a foundation, is Melanie also suffering from a substance use disorder? Devise a plan to address the problems she is experiencing.
