To assess the potential customer base's purchasing power

To evaluate the competition in the area

To determine the best location for the showroom

Outliers have no impact on the average

Outliers can significantly skew the average

By taking the average of the two middle values

By selecting the highest value

By selecting the lowest value

By taking the average of all values

Median is easier to calculate

Median is not affected by outliers

Mean is always inaccurate

Median is a more complex measure
