Question

8 7 12 7 11
10 7 12
Find:
a)the median
b) the range
c)the mode

Answer 1

a) Median: 9

b) Range: 5

c) Mode: 7

Explanation:

The median is the number in the middle.

First, you put the numbers in order: 7, 7, 7, 8, 10, 11, 12, 12

The middle of this is 8 and 10, so you plus them and divide by to 2, then it gives 9, so the median is 9.

To find the range, you minus the highest number and the lowest number, 12-7=5.

Mode is the most occurring and repetitive number, in this case, 7, because it is written 3 times.

Hope this helps!!!

Answer 2

`\boxed{\mathrm {Median = 9}}`

`\boxed{\mathrm{Range = 5}}`

`\boxed{\mathrm{Mode = 7}}`

Explanation:

The observations are:

8,7,12,7,11,10,7,12

In ascending order:

=> 7,7,7,8,10,11,12,12

A) Median => Middlemost no.

Median = 8,10

=>
`(8+10)/(2)`

=>
`(18)/(2)`

Median = 9

B) Range = Highest No. = Lowest No.

RANGE = 12-7

Range = 5

C) Mode => frequently occurring number

Mode = 7
