Assignment #3: Correlations Part 1: a) The two variables I have selected for the assignment are height and number of push-ups completed in one minute b) The scale of measurement used for height is ratio, and the scale of measurement used for the number of push-ups in one minute is ratio. Part 2: Will there be a significant relationship between height scores and push-ups completed in one minute? Part 3: a) There will be no significant relationship between height scores and push-ups completed in one minute H= Heigh PU= Push-ups H 0 : r H-PU = 0 b) There will be a significant positive relationship between height and push-ups completed in one minute H= Heigh PU= Push-ups H 1 : r H-PU > 0 Part 4: a) We conducted a Pearson correlation to address the relationship between height measurements and the number of push-ups performed in one minute. b) The assumption of homoscedasticity was met because the scatter plot appears to be mostly rectangular and box-shaped. c) We conducted a Pearson correlation to address the relationship between height measurements and the number of push-ups performed in one minute. There was a significantly small positive relationship between height (M = 170.4000, SD = 9.59) and push-ups performed in (M = 23.78, SD = 18.45; r = .398, p = <.001).

Part 5: Part 6: a) r = .398 b) R 2 = (.398) 2 = 0.158404 R 2 = 1.59% Part 7:
