1. Create a scatter plot between the children’s BMI and theiradoptive parents’ BMI. Format the plot into an APA-styled “figure”(see week 1 video for APA figure format). (3 points total: 1 forcorrect scatter graph type, 1 for correct data, 1 for APA format-figure number and title/caption)

1. Calculate the mean and standard deviation for the adoptiveparents’ BMI. (2 points total: 1 for mean and 1 for SD- deduct .5if the process is correct but result is wrong)

1. Calculate the Z scores for all the data points for the adoptiveparents. (1 point for calculating adoptive parents’ Z scores.Deduct .5 for each error in calculation)

1. Calculate the Pearson’s correlation coefficient rbetween children’s BMI and their adoptive parents’ BMI. Note thatthe children’s Z scores have been calculated in Part 1 of thisscenario. (2 points total: 1 for work, 1 for r value)

1. Explain the direction and strength of the relationship based onthe r. (2 points total: 1 for direction, 1 forstrength)

1. What is the proportion of shared variance between children’sBMI and their adoptive parents’ BMI? That is, how much of thevariance in the children’s BMI can be predicted from their adoptiveparents’ BMI? (2 points total: 1 for work, 1 for result)

1. Based on the two r statistics, what would be theanswer to the research question of whether children’s BMI isinfluenced more by nature or nurture? (1 point)
