Homoscedasticity and Heteroscedasticity
Follow the instructions below to demonstrate your understanding of homoscedasticity and heteroscedasticity.
Select 2 continuous variables from your dataset. You will use those variables to create a scatterplot using SPSS.
Copy and paste the scatter plot output to a Word document and label the scatterplot as heteroscedastic or homoscedastic.
Using the same 2 variables, change the data until you observe the opposite. (e.g, If the first scatter plot demonstrated heteroscedasticity, then create a scatter plot demonstrating homoscedasticity). You may wish to copy the data from the 2 original variables to create 2 new variables in which you can change the change the data to demonstrate the opposite condition.
Copy and paste the second scatter plot into the Word document and label the scatterplot as heteroscedastic or homoscedastic.
