Question

Using the set of numbers find the mean ( rounded to the nearest ) , median , mode and range .

Answer 1

Mean = 91

Median = 86

Mode = 98

Range = 11

a) Mean

To find the mean, we sum up the numbers and divide by the count

The count of the numbers is 6

We have the mean as;

`(98+98+90+82+89+87)/(6)\text{ = }(544)/(6)\text{ = 90.67 which is 91}`

b) To find the median, we will need to get the middle number

Since the count of the numbers is even, then we have two numbers at the middle

We have the median as the average of these two;

`(90+82)/(2)\text{ = 86}`

C) Mode

The mode is the highest in frequency (it means the number that re-occurs the most

The mode in this case is the number 98

d) Range

Range is the difference between the highest and smallest numbers

We have this as;

`98-87=\text{ 11}`
