Question

Transcribed Image Text:Classify each of the narratives below based on whether the mean or median provides a better description of
the center of its distribution.
commute time per day for an American adult
hours of sleep per day for an American adult
caloric intake per day for an American adult
age of natural death for the population of a major city
IQ scores for the population of a major city
age of first marriage for the population of a major city

Your answer is partially correct.
You have correctly selected 4.
The mean takes into account all of the values in a data set and is therefore affected by extreme values. For this
reason, the mean is typically used for symmetric distributions, where most of the values in the data set fall in
the center and there are few extreme values in both directions.
