PSY 2317 University of Houston Regression Equation of the Regression Model Questions
Goal Setting and GPACetin (2015) was interested in individual differences in goal setting behavior and performance in college students. To investigate the hypothesized association between the two variables, Cetin collected goal setting and grade point average (GPA) data from 166 college students. Goal setting was measured with a subscale from the Academic Self-Regulated Learning Scale. Students' GPA was measured via self-report. The goal_setting_gpa.csv data set simulates some of the data so that it corresponds to the results in the original study. We can use it to (a) the null hypothesis that there is no association between self-reported goal setting behavior and self-reported academic performance, and (b) construct a regression equation for predicting GPA from goal setting behavior.Cetin, B. (2015). Academic motivation and self-regulated learning in predicting academic achievement in college. Journal of International Education Research, 11(2), 95-106.(1) Download goal_setting_gpa.csv and open it in Jamovi.(2) Make sure the measure type and data type of the variables are correct.(3) From the Regression menu select Correlation Matrix. (4) In the Analysis panel, move gpa into the Variables box first and then goal_setting. We do it in this order because gpa is the variable we want to predict, which means that on a scatterplot, it should appear on the Y axis.(5) From the Correlation Coefficients menu select Pearson.(6) From the Hypothesis menu select Correlated.This specifies the alternative hypothesis, that the two varoables are correlated.(7) From the Additional Options menu select Report significance and N.(8) From the Plot menu select Correlation Matrix.(9) While still in the Analysis panel, from the Regression menu at the top, select Linear Regression.(10) Move gpa to the Dependent Variable box and move goal-setting to the Covariates box.(11) From the Model Fit menu select R, R2, and RMSE (which is the same thing as standard error of estimate).(12) Save the Jamovi file as Ch14_YourLastName.omv and use it to answer the questions on the worksheet.Instructions for submitting this assignment.(1) Locate Ch14_YourLastName.omv, and Ch14 Homework.docx where you saved them on your computer.(2) Click the title of this assignment (Ch14 Homework) to open the Upload Assignment page.(3) In the ASSIGNMENT SUBMISSION section, attach Ch14_YourLastName.omv and the Ch14 Homework file. Click Submit.(4) If you submit this assignment early enough, I might have time to provide feedback that you can use to improve it and possibly improve your grade. So soon after you submit it, return to this assignment to see if I've given you any feedback.

Exemplar, as they provide additional explanatory information. Consider
how you would extend a quantitative research to be appropriate for a
one-way ANOVA. Will prove the Data File for One-way ANOVA.sav. Must include the following:A description and justification for using the one-way ANOVAA properly formatted research questionA properly formatted H0(null) and H1 (alternate) hypothesisAn APA-formatted “Results” section for the one-way ANOVA
Identification of the statistical testIdentification of independent and dependent variables, including
the identification of the number of levels for the independent variableIdentification of data assumptions and assessment outcomeInferential results in correct APA statistical notation formatA properly formatted box plot
A discussion on how you would extend the one-way ANOVA to a
two-way ANOVA using the variables in the Data File for One-way
ANOVA.sav dataset.Properly APA-formatted referencesAppendix containing SPSS output (see Assignment Exemplar) Will need to cut and paste the SPSS output into the Appendix.SThe SPSS output is not in APA format, so you will need to type the information from the SPSS output to the appropriate sections of the APA table.

Statistics and Dating Discussion
Statistics has a wide range of real-world applications. The article “This Is What Happens When A Math Genius Hacks OkCupid” shows how statistics can be used to help someone meet the love of his or her life:
What if you could meet, woo, and win your fiancé in just 90 days? That's exactly what Chris McKinlay, a Boston mathematician, did in June 2012. McKinlay was working on his PhD at UCLA in June 2012 when he first joined OkCupid. After answering 350 questions from the thousands available on the site, he discovered that he only had a compatibility rating of over 90% with fewer than 100 women. Six disappointing dates later, and McKinlay realized that something needed to change. He decided to apply his data skills to his dating life.2
To complete the Discussion activity, please do the following:
Answer each question fully. Use a minimum of 250 words for a complete discussion post. While it is not required in this discussion, feel free to bring in outside resources to support your answers. Outside resources include materials outside of the textbook, such as a website.
Do you think it is plausible for someone to meet the person of his or her dreams by using statistics in experiments and decision making? Why or why not?
Do you think McKinlay’s approach would (or would have) worked for you? Why or why not?
How do you think you could use statistics to experiment or make decisions in other scenarios?

Scatter Diagrams
Scatter diagrams allow us to see relationships between two variables. Cite an example of two variables that might have a strong positive relationship. What would that scatter diagram look like? Next, cite an example of two variables that have very little relationship and describe what that scatter diagram would look like. Last, tell us why illustrating data in this way is helpful.
