a) What is the correlation between student cumulative GPA and the number of hours spent on school work each week? Be sure to include the computations or StatCrunch output to support your answer
Correlation between Q10 What is your cumulative Grade Point Average at Kaplan University? and Q11 How many hours do you spend on school work each week? is:
b) Is the correlation what you expected? No because I assumed the more hours you study the higher your GPA should be.
c) Does the number of hours spent on school work have a causal relationship with the GPA? Yes
