a) The mean is expressed as
sum of terms/number of terms
Mean = (131 + 133 + 145 + 129 + 145 + 134)/6
Mean = 817/6
mean = 136.2
b) To find the median, we would rearrange the terms in ascending order. Then we would find the middle number(s). By rearranging, it becomes
129, 131, 133, 134, 145, 145
The two numbers in the middle are 133 and 134. The median would be the average of both numbers.
Median = (133 + 134)/2 = 133.5
c) Mode is the term with the highest frequency. The term with the highest frequency is 145
Mode =
