Question

Find the mean, median, mode and range of the given

data. 4

14,18,19,20,21,18,16,21,24,21,18
​

Answer 1

Step-by-step explanation:

range of data is highest digit - lowest digit = 24-14= 10

mean = sum of the given no / total no

= 14+18+19+20+21+18+16+21+24+21+18/11

= 210/11= 19.09

mode= highest repeating term which is 18 and 21

for median arrange it into ascending order

14,16,18,18,18,19,20,21,21,21,24

as the total is 11 we can take first 5 one side and the last five one side we get the median 19 or as it is odd we can also calculate median by formula

n+1/2 where n is the no of term

11+1/2 = 6th term

which is 19
