Question

Find the mean, median and mode of:
18, 19, 20, 23, 22, 20, 17, 19, 25 and 20.

Answer 1

Since the repeated number is 20 then the mode is 20.

and we write as

17, 18, 19, 19, 20, 20, 20, 22, 23 , 25

mean= (18+19+20+23+22+20+17+19+25+20)/10

= 203/10

=20.3 Ans.

median= (10/2)+1 =5+1=6th term

= 20 Ans.
