Question

Collect the heights and weights of the family members
and prepare a tabular form and find mean, median, and mode

Answer 1

Answer:

Weight No. Of Students(x) xf cf

47 4 188 4

50 3 150 7

53 7 371 14

56 2 112 16

60 4 240 20

266 1061

Then, mean =

Σx

Σxf

=

266

1061

=3.99

Here, N=20 then

2

20

=10

In the table, cumulative frequency greater then 10 is 14 where value of x=53

Then, median is 53

In the given table, greatest frequency is 7 where value of x=53 then mode is 53.
