Question

Please help! I need the mean and median.

Answer 1

Mean = 2.21

Median = 2

Explanation:

The total frequency is 4 + 8 + 6 + 1 = 19.

The mean is the average (total days per total orders):

(4×1 + 8×2 + 6×3 + 1×4) / 19 = 2.21

Since there are 19 orders, the median is the 10th order, which took 2 days to ship.
