Find the mean, median and mode for (a) 22, 24, 23, 20, 19, 36, 24(b) 17, 14, 18, 16, 20, 16, 15, 16
Answers
(a) Median of the following number :-
Arranging the number in ascending order :-
19,20,22,23,24,24,36
Median of the number is 23.
(b) Median of the number :-
Arranging the number in ascending order :-
14,15,16,16,16,17,18,20
Median of the number is 16,16
Answer:
Step-by-step explanation:
mean:
a] 22+ 24+ 23+ 20+ 19+ 36+ 24 / 7 (no. of observations)
= 24 ans
b] 17 + 14 + 18 + 16 + 20 + 16 + 15 +16 / 8
= 16.5 ans
mode:
a] 24 as it occurs twice
b] 16 as it occurs thrice
median:
a] for this first arrange the nos. in ascending or descending order
19, 20, 22, 23, 23, 24, 36.
the number in the center is 23.
median is 23.
b] ascending order: 14, 15, 16, 16, 16, 17,18, 20.
in this case, we have even no. of observations.
we will find the mean of the two observations on middle
i.e. 16 + 16/ 2
= 32/ 2
= 16 ans
