The number of peas, in 30 pea pods, was observed as given below :
3,5, 4, 2, 1, 5, 2, 2, 4, 4, 3, ,3 4, 5, 6, 5, 4, 4, 2, 1, 1, 4, 5, 4, 5, 6, 4, 4, 4, 1
Prepare a frequency distribution table of the data.

In a 'tree plantation' project of a certain school there are 45 students of 'Harit Sena'.The record of trees planted by each student is given below:3, 5, 7, 6, 4, 3, 5, 4, 3, 5, 4, 7, 5, 3, 6, 6, 5, 3, 4, 5, 7,3, 5, 6, 4, 4, 3, 5, 6, 6, 4, 3, 5, 7, 3, 4, 5, 7, 6, 4, 3, 5, 4,4,7 Prepare frequency distribution table of the data.

Find the mean of the following data : Goals scored in 10 matches : 2, 2, 3, 5, 4, 2, 1, 3, 3, 4, 3

What is the mean of 1, 2, 3, 4, 5, 6, 7 ?

All 30 members of a 'Nature Club' in a school planted trees in the foundation day. The number of saplings planted by each member is given below. Prepare an ungrouped frequency distribution table:5, 4, 4, 6, 7, 4, 3, 5, 6, 4, 3, 7, 5, 4, 3, 2, 7, 6, 5, 3, 8,3, 2, 4, 5, 6, 5, 4, 4, 5

Solve : 3 2/5 - 2 1/4

In the school, 46 students of 9 th standard were told to measure the lengths of the pencils in their compass boxes in centimetres. The data collected was as follows:collected was as follows.16, 15, 7, 4.5, 8.5, 5.5, 5 ,6.5, 6, 10, 12, 13, 4.5, 4.916, 11, 9.2 7.3, 11.4, 12.7 13.916, 5.5, 9.9, 8.4, 11.4, 13.1, 15,4.8, 10, 7.5, 8.5, 6.5, 7.2, 4.5, 5.7, 16, 5.7 6.9, 8.9, 9.2, 10.2, 12.3, 13.7, 14.5, 10 By taking inclusive classes 0-5, 5-10, 10-15... prepare a grouped frequency distribution table
