Answer:
Order the set:
45, 45, 45, 45, 48, 56, 61, 71
Range:
Largest number - smallest number
71 - 45 = 26
Mode:
Most often [occuring] value.
45
Median:
Middle Value
n = number of values
if n is odd, the median is at position n/2
if n is even, the median is between position n/2 and n/2 + 1
n = 8
8 is even, so the median is between position 8/2 and 8/2 + 1
The median is between position 4 and 5
position 4 = 45
position 5 = 48
median = (45 + 48)/2
median = 83/2
median = 46.5
Mean:
45 + 45 + 45 + 45 + 48 + 56 + 61 + 71)/8
416/8
52
