Grades Summary

Complete the task using the grades data.

Task

  1. Call the summary() function on your grades_f variable to output the number of occurrences of each factor grade.
  2. Calculate the proportion of each grade, dividing the result of summary(grades_f) by the total number of observations using the length() function applied to the grades_f variable.

Task

  1. Call the summary() function on your grades_f variable to output the number of occurrences of each factor grade.
  2. Calculate the proportion of each grade, dividing the result of summary(grades_f) by the total number of observations using the length() function applied to the grades_f variable.
