it is a question of 8th class ​

Answer 1

Answer:

population ( in hundreds) of 50 towns and villages of a state, taken at random from a census report ar: 11,72,15,8,15,3,23,26,2,119,200,6,16,6,111,5,18,140,99,172,3172,18,30,43,2,1,52,40,3,7,13,5,142, 70,86,31,38,70,51,11,52,18,46,89,1,30,25,4,52 prepared a grouped frequency table for the above data, using class intervals 0-30,30-60,60-90 and so on. also find the class whith maximum frequency

Answer 2

The class with maximum frequency is 0-30

Given:

Populations(in hundreds) of 50 towns and villages of a state are: 11, 72, 15, 8, 15, 3, 23, 26, 2, 119, 200, 6, 16, 6, 111, 5, 18, 140, 99, 127, 31, 72, 18, 30, 43, 2, 1, 52, 40, 3, 7, 13, 5, 142, 70, 86, 31, 38, 70, 51, 11, 52, 18, 46, 89, 1, 30, 25, 4, 52

To find:

Prepare a grouped frequency table for the above data, using class intervals 0-30, 30-60,60-90 and so on.

Also find the class with maximum frequency.

Solution:

Grouped frequency table

• A grouped frequency table or frequency distribution is a way of organising a large data into more workable groups.

• To make a grouped frequency table we will make three columns as given below  

• The 1st column is for the class intervals.
• The middle column is for the tally marks.
• The 3rd column for frequency where we add up the tally marks  

The Grouped frequency table for given data is shown in figure

From the table we can conclude that the class with maximum frequency is 0-30
