To determine if a value is an outlier, we calculate the interquartile range (IQR) and then the upper fence. IQR = Q3 - Q1 = $169,000 - $81,000 = $88,000. The upper fence is Q3 + 1.5*IQR = $169,000 + 1.5*$88,000 = $301,000. Since $415,000 is greater than the upper fence, it is considered an outlier.
