Question

Bretts history quiz scores are 84, 78, 92, 90, 85, 91, and 0. Decide which measure(s) of center best describes the data set. Explain your reasoning.

Answer 1

the median best describes the data

the mean is less than 5 of the data points

the range only describes 2 of the data points

thus the median best describes the data

Explanation:

Median is the number in the centre of a set of observations

0. 78, 84,85,90,91,92, the median is 85

range = highest - lowest = 92 - 0 = 92

mean = sum of observations / number of observations = 74.3
