Question

Find mean median and mode of the following data . 12,11,15,13,18,11,13,12,13​

Answer 1

Step-by-step explanation:

Median is the middle number in the data set after arranging in ascending order. Here, middle number in the data set = 13. Sum of mode and median = 13 + 13 = 26. Hence, the sum of mode and median is 26.

Answer 2

Answer:

mean=13.1

median=13

mode=13

Step-by-step explanation:

mean = 12+11+15+13+18+11+13+12+13/9

=118/9

=13.1

median

data in ascending order

11,11,12,12,13,13,13,15,18

total observations(n) are 9, which is odd no.

median = n+1/2=9+1/2=10/2=5

so, 5th no. will be median i.e 13

mode

more repeated number is mode

so,13 is more repeated than any other number

mode = 13
