Week 12 (4/6 to 4/12)

The focus of this week is still on Chapter 10: Correlation and Regression. The goals are to learn the basic concepts in analyzing and modeling the correlation between two quantitative variables. You need to know the concept of linear correlation, computing the correlation coefficient, and be able to test statistical hypothesis on zero correlation. You need to know the basic concepts in regression modeling, be able to use SPSS to build basic regression models and interpret the model, be able to test and identify significant factor in the study, be able to model the response variable using quantitative variable, and be able to use SPSS for basic prediction for the response variable using the explanatory variable. All the test and regression modeling procedures can be done by SPSS. You need to be able interpret the SPSS output to conclude the analyses.

 

To Do List:

1. Read sections 1, 2, and 3 in chapter 10.

2. Download lecture notes and view recorded lecture for chapter 10 (V.41 and V. 42). (The lecture notes are on the right next to video links in the lecture video web page.)
