Question

Maggie takes three electives: art, Spanish, and creative writing. She calculated the mean absolute deviation of the points she earned throughout the year in each class.
art: mean absolute deviation of 2. 1


Spanish: mean absolute deviation of 0. 8


creative writing: mean absolute deviation of 2. 7


In which elective were her scores the most spread out?

Answer 1

Due to the higher value of the mean absolute deviation, her scores were most spread out in creative writing.

What is the mean absolute deviation of a data-set?

• The mean of a data-set is given by the sum of all observations divided by the number of observations.

• The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.

• The mean absolute deviation represents the average by which the values differ from the mean. Hence, a higher value of the mean absolute deviation means that the data-set is more spread out.

In this problem, creative writing has the highest mean absolute deviation, hence, it is the elective in which her scores were most spread out.
