## Relative Cumulative Frequency Distribution

The cumulative frequency divided by the total frequency is called relative cumulative frequency or percentage cumulative frequency. It is used to know the percentage of observations falling below a certain specified value. A table showing relative cumulative...

## How to Calculate Cumulative Frequency Distribution

Cumulative frequency distribution shows the number of observations which fall below or above in a given class interval. If the number of observations fall below in a given class interval then it is called less than cumulative frequency distribution. On the other hand...

## How to Construct a Relative Frequency Distribution

Frequency of a class divided by total frequency of all classes is called relative frequency. Relative frequency is expressed in terms of percentage therefore it is also known as percentage distribution. A table showing intervals with corresponding relative frequencies...

## Frequency Distribution Table

Now we know about class interval, class limits, size of class interval, frequency distribution, class boundaries and mid class. On the basis of all these concepts, we are now able to construct a frequency distribution table with the help of problem A.  Problem A:...

## Calculation of Class Boundaries and Mid. Class

Calculation of Class Boundaries Calculation of class boundaries for three class intervals can be illustrated with the help of following figure. The figure shows two methods for calculating the class boundaries. In the first method, class boundaries are calculated by...

## How to Calculate Frequency Distribution

The arrangement of data according to magnitude or size is called a frequency distribution. It is the method of putting data into different groups which are called class intervals or simply classes. From the frequency distribution comes the concept of grouped data...
