Question: Complete the Test 2, Correlation Coefficient and Regression test that examines the relationship between public school poverty rate and college readiness. - PLEASE DO NOT FORGET TO GRAPH ON PAGE 2 AND PAGE 4 (STEP 2) according to the example
Pearson r Correlation Coefficient and Regression Measure the relationship between public school poverty rates and percentage of students that passed the college readiness benchmark by 1) creating a scatter plot, 2) conducting a Pearson / Test and appropriate post-hoc test(s), and 3) finding and reporting regression equation and standard error of the estimate (if applicable). Provide an interpretation of all of your results.
