Dr. Love is interested in the difference between people with different styles of love (eros, ludic, storge) and the number of romantic partners that they have had in their lifetime.
Use analysis of variance to test if the type of love style influences the number of romantic partners someone has.
If there is a significant difference, use a post hoc test to explain them.
Write all of the results in APA style.
Dr. Love is interested if there are differences between genders and the number of partners, love style and the number of partners, and the interaction between gender and love style and the number of partners.
Using a FACTORIAL ANOVA, test for differences between genders, love style, the interaction between the two on the number of partners each participant has had.
If these results are significant please interpret them, using post hoc analyses when possible.
Report results in APA style.
Use the Love Styles Data Set for these problems
Dr. Nancy wants to know how effective the therapy is at St. Maximus inpatient facility. Specifically, she wants to test if (regardless of the therapist) the patient's depression symptoms change from therapy session one, therapy session two, and therapy session three.
Use a repeatedmeasures analysis of variance to test if there is a significant difference in depression symptoms across the 3 times.
If there is a significant difference, use Post hoc tests to explain them.
Write all of the results in APA style.

Part 1
Dr. Nadler is interested in the relationship between extraversion, agreeableness, and neuroticism scores on a personality test.
Calculate a correlation coefficient for these relationships using the Pearson statistic.
Report all significant and nonsignificant relationships in APA style.
Using the Jamovi Scatr Function, create 3 scattergrams/scatterplots. For each scatterplot, include the grouping variable of Gender.
The first should depict the relationship between extraversion and agreeableness.
The second is between extraversion and neuroticism.
The third is the relationship between agreeableness and neuroticism.
Use the Personality Data Set for these problems
Part 2
Dr. Nadler has also created a survey to measure students’ perceived advisor support. He hopes these 14 questions are reliable in measuring students’ perceptions of their advisors.
Test the reliability of this survey using Cronbach’s Alpha.
Interpret the output and tell me if this is a reliable measure based on this test.
If there are items that need to be reverse scored, please complete the reverse scoring and rerun the analysis, and then interpret the output again.
Compute the average perceived advisor support variable
Run a correlation between the average perceived advisor support variable and the variable labeled id and report the results in APA style.
