A student wants to report on the number of movies her friends watch each week. The collected data are below: 0 , 0 , 1 , 1 , 2 , 2 , 2 , 14 Which measure of center is most appropriate for this situation and what is its value? Group of answer choices Median, 1.5 Median; 3 Mean, 1.5 Mean; 3

Answer 1

Answer: median = 1.5

Step-by-step explanation:

The mean is the most common measure of center which is synonymous to average. However, the mean is affected by extreme values so it may not be the best measure of center to use in a skewed distribution.

The median is the value in the center of the data. Half of the values are less than the median and half of the values are more than the median. It is probably the best measure of center to use in a skewed distribution.

The median of

0 , 0 , 1 , 1 , 2 , 2 , 2 , 14

Median = (1+2)/2 = 1.5
