Question

The following data gives the information about the number of children in 21 families in a locality. 2,1,3, 4,2,2, 1,3, 2,6, 4, 3, 3,2,1.1,3,2.1. 1.2

(a) Find the mode of the data by tahulating the observations

(b) Find the median and mean of the data​

Answer 1

Step-by-step explanation:

mode=2

median=16/2=8,4

Answer 2

Answer:

a) mode = 2 , highest number of frequency.

b) median = 11

total number = 21 (odd)

(n th + 1 /2 ) , n = 21

21+1/2 = 22/2 = 11

therefore median = 11 .

c) mean =  

mean = sum of observations / no of observations

2+1+3+4+2+2+1+3+2+6+4+3+3+2+1+1+3+2+1+1+2+/21+

=49/21=2.333....

therefore mean = 2.333.....
