Example of frequency distribution with uneqal classe
Answers
Step-by-step explanation:
The frequency of any value is the number of times that value appears in a data set. So from the above examples of colours, we can say two children like the colour blue, so its frequency is two. So to make meaning of the raw data, we must organize. And finding out the frequency of the data values is how this organisation is done.
Frequency Distribution
Many times it is not easy or feasible to find the frequency of data from a very large dataset. So to make sense of the data we make a frequency table and graphs. Let us take the example of the heights of ten students in cms.
Frequency Distribution Table
139, 145, 150, 145, 136, 150, 152, 144, 138, 138
Frequency distribution table
This frequency table will help us make better sense of the data given. Also when the data set is too big (say if we were dealing with 100 students) we use tally marks for counting. It makes the task more organised and easy. Below is an example of how we use tally marks.

Using the same above example we can make the following graph:
