Lesson: Best Measure of Central Tendency Mathematics • 6th Grade
In this lesson, we will learn how to choose and evaluate the appropriate measure of the central tendency (average) of a given data set.
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?
A group of girl scouts is selling boxes of cookies to raise money for charity. The line plot shows how many boxes of cookies they sold. State whether the mean would be a good measure of central tendency for the data or not. Explain your answer.
