Types of Frequency Distributions
There are two types of frequency distributions that are,
- Simple Frequency Distribution
- Cumulative Frequency Distribution
- Relative Frequency Distribution
Now lets learn about them in detail.
Simple Frequency Distribution
A simple frequency distribution is a basic type where the data is organized into non-overlapping class intervals, and the frequency of each interval is listed. Each class interval represents a range of values, and the corresponding frequencies show how many times values fall within those ranges. This type provides a clear overview of the distribution of data.
Cumulative Frequency Distribution
In a cumulative frequency distribution, the frequencies are accumulated or added up as you move through the class intervals. The cumulative frequency of a particular interval includes the frequencies of all the previous intervals. This type helps in understanding the total occurrence of values up to a certain point in the dataset and is useful for analyzing the overall pattern of the data.
Relative Frequency Distribution
A relative frequency distribution expresses the proportion of the total dataset that each class interval represents. It is calculated by dividing the frequency of each interval by the total number of observations. This type provides a percentage or decimal representation of the contribution of each interval to the overall dataset. It helps in comparing the importance of different intervals in relation to the entire dataset.
Frequency Distribution Table
Frequency Distribution Table in statistics is a table that contains all the values and frequencies of different objects. It is an efficient way to record and retrieve a big chunk of data. It helps in easy visualization of data based on its frequency which basically means how many times a particular data appears.
In this article, we will learn about, Frequency Distribution Table Definition, Examples, How to Make Frequency Distribution Table, and others in detail.
