Griffin wants to get an accurate picture of household salaries in his neighborhood. The salaries for people in his neighborhood are 87,000; 94,000; 103,000; 97,000; and 55,000. What measure of central tendency will most accurately describe the data? Find the mean and median of this data.
Because there is an outlier (55,000) the median will be the most accurate way to describe the data. Mean: 87,200 Median: 94,000
