Worked examples
On a frequency table, what does the FREQUENCY column show?
- How many times each value occurs.
- The values themselves.
- The order.
- The total.
Answer: How many times each value occurs.. Frequency = count of occurrences.
A sports team scored 12, 18, 25, 7, 18 goals in 5 matches. Find the MEAN.
- 16
- 18
- 12
- 80
Answer: 16. Sum 80 ÷ 5 = 16.
Why does adding 10 to every value in a data set change the MEAN but not the RANGE?
- Mean depends on each value (so it increases by 10). Range depends only on the GAP between max and min (which is unchanged).
- Coincidence.
- Convention.
- Mean uses different maths.
Answer: Mean depends on each value (so it increases by 10). Range depends only on the GAP between max and min (which is unchanged).. Range = max−min; shift cancels.
