Front

Find the median of the following numbers: 7, 2, 5, 10, 3.

Back

Median = 5 (after arranging the numbers: 2, 3, 5, 7, 10) - the middle number.

Front

Find the mode of the following numbers: 1, 2, 2, 3, 4.

Back

Mode = 2 (it appears most frequently).

Front

Find the range of the following numbers: 10, 15, 20, 5.
