1. In each case, indicate which correlation is stronger or weaker as specified. (2 points each)

1. Which correlation is stronger, r =.23 or r = -.65?
2. Which correlation is weaker, r = .67 or r = .43
3. Which correlation is stronger, r = .32 or r = -1.0?
4. Which correlation is weaker, r = -.98 or r = .23?
5. For each of the following two sets of scores:

Use the following data for questions 7 - 10.

. In a study on mother-child interaction, a research assistant watched a video tape of five children interaction with their mothers. He counted the number of minutes each child spent clinging to its mother (Y). He also determined the age of each child, in months (X). The data are given below.

X ( age in months) Y ( minutes clinging)

Child 1: 11 31

Child 2: 49 9

Child 3: 24 26

Child 4: 17 27

Child 5: 37 13

1. Calculate the correlation coefficient by hand. (File upload) (20 points
2. Compute the correlation coefficient in Jamovi and paste the output below or upload your outputs as a separate file in the assignment. (5 points)
3. Find the regression equation using Jamovi. Copy and paste your Jamovi output here or upload your outputs as a separate file in the assignment (10 points)
4. How long would you predict a child who is 20 months to spend clinging to their mother? (5 points)
