Question

Find the mean of 19, 25,20,9,20,15,10,5,16,25,20,24,12,20​

Answer 1

Answer:

mean=sum of all observation/total number of observation

mean=19+25+20+9+20+15+10+5+16+25+20+24+12+20/14

mean=240/14

mean=17.14

Answer 2

Step-by-step explanation:

Given that

19,25,20,9,20,15,10,5,16,25,20,24,12,20

To find mean

Solution

Total numbers is 14.

hence

$mean = \frac{sum \: of \: all \: numbers\:}{total \: numbers}$

$mean = \frac{19 + 25 + 20 + 9 + 20 + 15 + 10 + 5 + 16 + 25 + 20 + 24 + 12 + 20}{14}$

$mean = \frac{240}{14}$

$mean = 17.14$

mean is 17.14.
