Question 13
We want to assess the relationship between class rank and how many minutes a person spends on
social media. We randomly select 5 students from UMD and have them report their class rank and
number of minutes per week they spend on social media. We get the following data.
Because class rank is ordinal data, we want to compute Spearman's rho. Please compute the
numerator for Spearman's rho and use 4 decimal places for all computations and final answer.
