Lesson 8: Testing Significance of Slope and Overall Model (ttest and Ftest)
Thu, Feb 16
Review:
 Correlation
 Linear Regression
Presentation:
 ttest of slope:

 Ftest of overall model:
 Data Set 3 in Sheets
Activity:
 Calculate ttest of slope and Ftest for Data Sets 1 and 2 (by hand)
 Data set 1: {(3,5), (5,8), (8,11), (12,10)}
 Data set 2: {(50,12), (60,15), (70,20), (80,30)}
 Use this data set: East Pueblo RE Sales 20142016 (from last time)
 Find the necessary values from your Regression Output
 Calculate ttest of slope and Ftest for these data (by hand)
 Compare to ttest and Ftest values on Regression Output (there may be differences due to rounding error)
