Data Analysis of Jersey Numbers

Data: 78, 81, 54, 2, 26, 13, 66, 23, 77, 15, 3
Mean: (Sum of values) / (Number of values) = 44.36, approximate

Midrange: (Highest value + Lowest value) / 2 = (81 + 2)/2 = 41.5

Interpretation of Results

Midrange: This measure shows the range of the data.
Mode: In this data set, it is not useful as there is no repeated value.
Nominal Data: Jersey numbers are categories and thus the statistical measure is not meaningful in a typical sense. The numbers just assigned to represent categories.
