8.1 What is the correlation between student’s height and parent’s height? Also produce a scatterplot. Interpret the results, including statistical significance, direction, and effect size.

8.2 Write a question that can be answered via correlational analysis with two approximately normal or scale variables. Run the appropriate statistics to answer the question. Interpret the results.

8.3 Make a correlation matrix using at least four appropriate variables. Identify, using the variable names, the two strongest and two weakest correlations. What were the r and p values for each correlation? 

8.4 Is there a combination of gender at birth and same-sex parent’s height that significantly predicts student’s height?
