Topic 5: Benchmark- Correlation and Regression Linh Dang Grand Canyon University: PSY-520 February 12, 2020 This study source was downloaded by 100000831988016 from CourseHero.com on 05-06-2022 05:16:56 GMT -05:00 https://www.coursehero.com/file/55158147/Topic-5-Benchmarkdocx/ PSY-520 Graduate Statistics Topic 5 – Benchmark – Correlation and Regression Project Directions: Use the following information to complete the questions below. While APA format is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center. 1. Select at least three variables that you believe have a linear relationship. a. Specify how you will measure each of these variables (i.e., what instrument will you use and provide an APA reference for the instrument) Statistics (2019) stated that a linear relationship means that you could represent the relationship between two different variables with a line. In other words, according to Witte and Witte (2017), the linear relationship is one straight line in a graph. A linear relationship exists when plotting on the graph creates a straight line and this straight line shows the direction and the rate of change of one variable translates to the changes in the other variable. The example that is presented in this will be when someone buys a car and the loan agent have to determine if there would be a relationship between the buyer’s income and the price car that they are buying. -Independent variable: Income -Dependent variable: Price -Third variable: Loan amount This study source was downloaded by 100000831988016 from CourseHero.com on 05-06-2022 05:16:56 GMT -05:00 https://www.coursehero.com/file/55158147/Topic-5-Benchmarkdocx/ The third variable is used to serve as the means to assist in eliminating cases as the outliners. The third variable isn’t to be incorporated into SPSS Statistic strategy despite the fact that a valuable device. 2. Collect the data for these variables and describe the data collection technique and why it was appropriate as well as why the sample size was best. a. Submit the data collected by submitting the SPSS data file with your submission. The dependent variable is price. The unstandardized coefficients priced at 8286.786 while the income is at 0.564. The regression equation is 8286.786+0.564 is the significance for both variable at 0.000 which is right in the middle of the correlation coefficient.

Find the Correlation coefficient for each of the possible pairings of variables and describe the relationship in terms of strength and direction. The linear model for the example of the price of car and income. 4. Find a linear model of the relation
