    Median is a better measure of center than the mean (average)

    a) 56,62,68,71,104,507 ⇒ Median is a better measure. Mean is not a better measure because of the outliers.

    b) 2,8.5, 9.2, 9.8, 10.1 lb ⇒ Median is a better measure.

    c) Mean is a better measure. No outliers. Data set values are close with each other.

    d) Mean is a better measure.
