Question

A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city. The data obtained for 30 days is as follows.0.03 0.08 0.08 0.09 0.04 0.17
0.16 0.05 0.02 0.06 0.18 0.20
0.11 0.08 0.12 0.13 0.22 0.07
0.08 0.01 0.10 0.06 0.09 0.18
0.11 0.07 0.05 0.07 0.01 0.04
Make a grouped frequency distribution table for this data with class intervals as 0.00 - 0.04, 0.04 - 0.08, and so on.

Answer 1

Hello,

Solution:

Given data

0.03 0.08 0.08 0.09 0.04 0.17
0.16 0.05 0.02 0.06 0.18 0.20
0.11 0.08 0.12 0.13 0.22 0.07
0.08 0.01 0.10 0.06 0.09 0.18
0.11 0.07 0.05 0.07 0.01 0.04

For grouping in given class ,there are two possible grouping(Inclusive form) and exclusive form

1) Group frequency distribution table : 0.00-0.04 (0.04 not included)

class __________ frequency

0.00-0.04__________4

0.04-0.08 _________9

0.08-0.12__________8

0.12-0.16___________3

0.16-0.20___________4

0.20-0.24__________2

2) Group frequency distribution table : 0.00-0.04 (0.04 included)

class __________ frequency

0.00-0.04__________6

0.04-0.08 _________11

0.08-0.12__________6

0.12-0.16___________2

0.16-0.20___________4

0.20-0.24__________1

Hope it helps you
