Main Module 2
Simple Linear Regression and Correlation

 

Learning Objectives

At the end of the module, the student will:

 Know that regression analysis concerns the form and direction of the relationship between variables; and is used for prediction. 

Know that correlation analysis concerns the strength of the relationship between variables

Enter data for an independent and a dependent variable using Microsoft Excel and generate a scatter diagram plot. Insert a trend line, regression equation and coefficient of determination on the plot.

  Generate a regression analysis, line fit plot, residual plot with prediction intervals, normal probability plot, and correlation coefficient in Microsoft Excel.

Interpret regression coefficients, practical utility, statistical utility of the regression model; and interpret the correlation.

  Evaluate the assumptions of a regression.

  Use regression model for prediction.
