Question

Find Mean, Mode, Median of given data
10,7,8,5,8,13,11,12,15,16,16,12,19,20,12,16,20,16,16​

Answer 1

Step-by-step explanation:

arrange in ascending order

use mean=sum of observations/no. of obser.

mode =16

median use formal

Answer 2

The mean, mode and median for the given data are as follows.

Given,

10,7,8,5,8,13,11,12,15,16,16,12,19,20,12,16,20,16,16​

First we need to arrange the data in ascending order

5, 7, 8, 8, 10, 11, 12, 12, 12, 13, 15, 16, 16, 16, 16, 16, 19, 20, 20

Mean = ( 5+7+8+8+10+11+12+12+12+13+15+16+16+16+16+16+19+20+20 ) / 19

= 252 / 19

Mean = 13.26

Median = middlemost term.

Since there are 19 terms, we have, 19/2 = 9.5 ≈ 10

10th term will be the median.

The 10th term of the series is 13

Median = 13

Mode is the most frequent term

In the data 16 has a frequency of 5.

Therefore, the mode is given as,

Mode = 16
