Question

Find the mean median mode and range. 2, 4, 7, 15, 7, 4, 5, 4

Answer 1

Mean: 6

Median: 4.5

Mode: 4

Range: 13

Explanation:

Answer 2

mean = 6

median = 4.5

mode = 4

range = 13

Explanation:

To find the mean, median, mode and range firstly place the numbers in ascending order.

2, 4, 7, 15, 7, 4, 5, 4

= 2, 4, 4, 4, 5, 7, 7, 15

Mean:

(Mean is the average of all the data in a set.)

`\\ \tt2, 4, 4, 4, 5, 7, 7, 15`

`\\ \tt = (2 + 4 + 4 + 4 + 5 + 7 + 7 + 15)/(8)`

`\\ \tt = (48)/(8)`

`\\ \bold{\tt = 6}`

Median:

(Median is the middle number of the set.)

2, 4, 4, 4, 5, 7, 7, 15

median

= 4+5/2

= 9/2

= 4.5

Mode:

(Mode is the number which appears multiple times.)

2, 4, 4, 4, 5, 7, 7, 15

mode = 4

Range:

(Range is the number which comes by subtracting the smallest number to the largest number.)

2, 4, 4, 4, 5, 7, 7, 15

Largest number = 15

Smallest number= 2

range

= 15-2

= 13
