Question

Find the mean , median and mode for the following set of values :
13, 18 , 13 , 14 , 13 , 16 , 14 , 21 , 13

Answer 1

Answer:

The median is the middle value, so to rewrite the list in order: 13, 13, 13, 13, 14, 14, 16, 18, 21.

Step-by-step explanation:

mode is 13

There are nine numbers in the list, so the middle one will be (9 + 1)/2 =5 = 5th number, So the median is 14. •

Answer 2

Answer:

MEAN=15

MEDIAN=14

MODE=13

Step-by-step explanation:

MEAN=(13+13+13+13+14+14+16+18+21)÷9 = 15

MEDIAN= (N+1)÷2 = (9+1)÷2= 5th term = 14 when arranged in ascending order.

MODE=highest frequent value = 13
