Question

Find mean, mode and median for the following data:
16, 15, 18, 10, 10, 20, 10, 20, 15, 21, 15 and 25.​

Answer 1

Answer:

PLZ MARK AS BRAINLIEST !

Step-by-step explanation:

1. MEAN..

= SUM OF OBSERVATIONS/TOTAL NO. OF OBSERVATIONS.

= 16 + 15 + 18 + 10 + 10 + 20 + 10 + 20 + 15 + 21 + 15 + 25 / 12

= 195 / 12

= 16.25

2. MEDIAN

= The median is the middle value, so first I'll have to rewrite the list in numerical order :

= 10 : 10 : 10 : 15 : 15 : 15 : 16 : 18 : 20 : 20 : 20 : 21 : 25

= 15 + 16 / 2

= 15.5

3. MODE.

The mode is the number that is repeated more often than any other.

=10 and 15

Answer 2

Answer:

mean= 16.25

mode = 10, it occurs 3 times

median = Ascending order - 10,10,10,15,15,15,16,18,20,20,21,28

median =15
