Easy Statistics question...

In a sample's distribution of income, the modal income (mode, or most frequently occurring observation of income) is $27,000 a year, the median income is $35,000 a year, and the mean income is $45,000 a year. Which statistic do you think is the best estimate of average income, and would you say that income is normal, skewed to the left, or skewed to the right?

$27,000, skewed right

$35,000, skewed right

$45,000, normal

$35,000, skewed left

$45,000, skewed left

ok... the data has a positive skew

The data is money, which is quantitative, so eliminate mode. 

The positive skew means that an outlier to the right is having a big influence on the mean. 

When outliers occur, the median is the best measure of the centre of a data set.
