Question

Find the mean, median, mode, and range of the data set.

9, 3, 15, 7, 2, 4, 3
If necessary, round your answers to the nearest tenth.

Answer 1

Explanation:

Mean = Sum of data ÷ number of data set

`=(9+3+15+7+2+4+3)/(7)\\\\=(43)/(7)\\\\= 6.14\\\\= 6.1`

Median:

Arrange the data in ascending order:

2 , 3 , 3 , 4 , 7 , 9 , 15

Middle term is the median of the data set

Median = 4th term = 4

Mode:

Mode is the data whose is frequency is more.

So, mode = 3

Range = Maximum - minimum

= 15 - 2

= 13
