Answer:
Step-by-step explanation:
(a) MEAN = £fx/ fx (The sum of the all jerseys number/ number of jerseys)
= 680/11
= 61.8
(b) MEDIAN = The middle number when all the items are arranged either in ascending order or descending order
= 6, 14, 50, 51, 54, 68, 77, 78, 89, 94, 99
= 68
(Strike out the numbers, the middle number left is the median)
(c) MODE= (Mode implies the number with the highest frequency)
From those items, THERE IS NO MODE.
All the items (numbers) appeared once
(d) MID-RANGE:
This is the sum of the least valued number and the greatest valued number and dividee by two
Mid-range = (99 + 6) / 2
= 105/2
= 52.5
(e). The results tells us that:
The mean and median give two different interpretations of the average (or typical) jersey number, while the midrange shows the spread of possible jersey numbers
Also, pls note that the median implies the measure of the middle of the sets of jerseys number. And the mean tells us the distribution of the sets of jerseys number.
Hope this helped!
