Statistics

(NCERT Ex 14.1)

Q1: A survey was conducted by a group of students as a part of their environment awareness programme, in which they collected the following data regarding the number of plants in 20 houses in a locality. Find the mean number of plants per house.


Answer:

We use the following relation to find the class mark (x_i) for each interval:

Class mark (x_i) =

Calculating x_i and f_ix_i as follows:

Number of plants	Number of houses(fi)	xi	fixi
0 -2	1	1	1 ☓ 1 = 1
2 -4	2	3	2 ☓ 3 = 6
4 -6	1	5	1 ☓ 5 = 5
6 -8	5	7	5 ☓ 7 = 35
8 - 10	6	9	6 ☓ 9 = 54
10 -12	2	11	2 ☓ 11 = 22
12 - 14	3	13	3 ☓ 13 = 39
Total	20		162

From the table, it is observed that

Σ f_i = 20

Σ f_ix_i = 162

Mean , x =

= = 8.1

Therefore, mean number of plants per house is 8.1.

Here, direct method has been used as the values of class marks (x_i) and f_i are small.


Q2: Consider the following distribution of daily wages of 50 worker of a factory.

Daily wages(in Rs)	100 - 120	120 - 140	140 - 160	160 - 180	180 - 200
Number of workers	12	14	8	6	10

Find the mean daily wages of the workers of the factory by using an appropriate method.
