Assignment 6: Explore Relationships Between Variables Using Correlation, Regression, and Chi-Square
Part I. Correlation and Linear Regression Imagine a researcher is interested in examining the relationship between self-esteem (Self_Estm) and productivity (Prod). The researcher is also interested in the ability to predict the productivity of teachers using years of teaching (Experience) as the predicting variable. Use the “teacher’data.sav” dataset to conduct the analysis involving Self_estm, Prod, and Experience. Use this data to answer the questions below (these data have already been entered into the “teacher’data.sav” SPSS file). Table 3 “teacher’data.sav” Dataset
In this assignment, you will expand your understanding of inferential statistics involving correlation and linear regression. Complete the following: 1. Produce an SPSS analysis for a correlation between participants’ self-esteem and productivity.
2. Produce an SPSS analysis using linear regression to examine whether participants’ years of experience predict their productivity.
Part II. Chi-Square You will be entering and analyzing the following data in SPSS. When entering the data, please use 1 for Red, 2 for Yellow, and 3 for Green. Make sure that you go to the variable view window and enter these values in the label box. Twenty senior students were asked to choose the color they preferred for their senior-class shirt. Conduct a chi-square goodness-of-fit test to test the null hypothesis that says there is no true difference in the population from which the sample was drawn. Table 4 Red, Yellow, and Green Data
