✓

Answer

The objectives of classification of data are:
  1. To make the data simple and brief: The main objective of classification is to condense the large data to make them easily understood. For example, if there are 100 students in a class then their marks can be put in the following way:
Marks Obtained (Out of 100)
No. of students
20-40
15
40-60
25
60-80
50
80-100
10
Total
100

Wieghts in kgs.
