The daily maximum temperatures (in degree Celsius) recorded in a certain city during the month of November are as follows:

Represent them as a frequency distribution table with class size 1°C.

Given:

The daily maximum temperatures (in degree Celsius) recorded in a certain city during the month of November are:

25.8, 24.5, 25.6, 20.7, 21.8, 20.5, 20.6, 20.9, 22.3, 22.7, 23.1, 22.8, 22.9, 21.7, 21.3, 20.5, 20.9, 23.1, 22.4, 21.5, 22.7, 22.8, 22.0, 23.9, 24.7, 22.8, 23.8, 24.6, 23.9, 21.1

To do:

We have to represent the data as a frequency distribution table with class size 1°C.

Solution:

Maximum temperature $= 25.8^o\ C$

Minimum temperature $= 20.5^o\ C$

Range $= 25.8 - 20.5$

$= 5.3^o\ C$

The required frequency distribution is: 

Temperature	Tally marks	Number of days
20-21	|||| |	6
21-22	||||	5
22-23	|||| ||||	9
23-24	||||	5
24-25	|||	3
25-26	||	2
