Question 10 • Mathematics for Data and Financial Literacy

A tax policy researcher examines the distribution of household incomes and observes it is highly skewed to the left. Which statement best describes the characteristics of this distribution?

Answer
A
The distribution has a symmetrical shape.
B
The mean and median are approximately equal.
C
The mean is greater than the median.
D
The median is greater than the mean.

Explanation

In a left-skewed distribution, the long tail extends toward lower incomes. Those unusually low values pull the mean downward more than they affect the median, so the median is greater than the mean. Therefore, the best description is “The median is greater than the mean.”
