Shown are the exam scores of 10 students.
Calculate the mean score.
Calculate the median of the scores.
Explain which of these measures of central tendency better represents a typical score in the exam.
A data set has 20 different values: 18 of the values are between 10 and 20 but 2 of the values are greater than 40. Which measure of central tendency would better represent a typical value of the data set?
The following table shows the greatest distances thrown by the finalists in the discus competition of the 2016 Rio Olympics for both men and women.
