bookChallenge: Compute Summary Statistics

Tâche

Swipe to start coding

You are given a data frame math_scores containing exam scores for a group of students. Your task is to calculate and interpret key summary statistics for these scores.

  • Calculate the mean (average) and assign it to mean_math.
  • Calculate the median (middle value) and assign it to median_math.
  • Calculate the mode (most frequent value) and assign it to mode_math.
  • Find the minimum score and assign it to min_math.
  • Find the maximum score and assign it to max_math.
  • Calculate the standard deviation and assign it to sd_math.

Use R functions to compute each statistic and assign the result to the specified variable. This will help you explore the central tendency and spread of the data. If there is no repeated value, select the smallest value when finding the mode.
