Linear Regression
Input data into the spreadsheet or drag the points to create your data set. Try to estimate the line of best fit by dragging the grey diamonds. What results do you get?
1) How strong is your correlation? How can you tell?
2) Is a linear regression appropriate for the data you chose? Why or why not?
3) Can you come up with a set of data that is not appropriate for linear regression? What does it look like?
4) What is an example of something your data might represent?
