Cumulative frequency 0 17 32 37 53 58 65

Construct a frequency distribution table for the numbers given below, using the class intervals
21 – 30, 31 – 40 ………… etc.
75, 65, 57, 26, 33,44, 58, 67, 75, 78, 43, 41, 31, 21, 32, 40, 62, 54, 69, 48, 47, 51, 38, 39, 43, 61, 63, 68, 53, 56, 49, 59, 37, 40, 68, 23, 28, 36 and 47.
Use the table obtained to draw: (1) a histrogram (2) an ogive 

Use the information given in the adjoining histogram to construct a frequency table.
 Use this table to construct an ogive. 

  

 

Class mark 12.5 17.5 22.5 27.5 32.5 32.5 42.5 
Frequency 12 17 22 27 30 21 16

(a) From the distribution, given above, construct a frequency table.
(b) Use the table obtained in part (a) to draw: (i) a histogram, (ii) an ogive 

Use graph paper for this question.
The table given below shows the monthly wages of some factory workers
(i) Using the table, calculate the cumulative frequencies of workers
(ii) Draw a cumulative frequency curve.
Use 2 cm = ₹ 500, starting the origin at ₹ 6500 on x-axis, and 2 cm = 10 workers on the y – axis. 

Wages (in Rs) 6500-7000 7000-7500 7500-8000 8000-8500 8500-9000 9000-9500 9500-10000
No of workers 10 18 22 25 17 10 8

The following table shows the distribution of the heights of a group of factory workers: 

Ht. (cm) 150 - 155 155 – 160 160 - 165 165 – 170 170 – 175 175 - 180 180 – 185 
No of workers: 6 12 18 20 13 8

(i) Determine the cumulative frequencies.
(ii) Draw the ‘less than’ cumulative frequency curve on graph paper. Use 2 cm = 5 cm height on one axis and 2 cm = 10 workers on the other. 

Construct a frequency distribution table for each of the following distributions 

Marks (less than) 0 10 20 30 40 50 60 70 80 90 100
Cumulative frequency 0 7 28 54 71 84 105 147 180 196 200

 

 

Construct a frequency distribution table for each of the following distributions 

Marks (less than) 0 10 20 30 40 50 60 70 80 90 100
Cumulative frequency 100 87 65 55 42 36 31 21 18 7 0
