Explanation / Answer

The spread is the range, which equals: 71-15 = 56

Yes the distribution contains an outlier, the value 71 is an outlier.

Median of distribution is: 22

Mean of the distribution is: 27.2

Mean is different than median because median is resistant to outliers, and is a more accurate estimate of central tendency of a distribution that includes outliers.
