please see detailed answers below
Explanation:
Mean = (sum of the numbers) / (size of data set)
(32 + 87 + 67 + 32 + 32 + 87 + 77 + 25) /8 = 54.9
Median = middle value when data is arranged in ascending order
8 values, so we need the number halfway between the 4th and 5th value.
in order: 25, 32, 32, 32, 67, 77, 87, 87.
4th value is 32, 5th value is 67.
halfway between is (32 + 67) / 2 = 49.5. this is the median value.
Mode = most common value
there are three 32s, two 87s. all other values appear only once. so 32 is the mode.
Range = largest value – smallest value
87 - 25 = 62
