Frequency Distribution
Define Frequency Distribution in Statistics
A frequency distribution is a table or graph that displays the frequency of various outcomes or values in a sample or population. It shows the number of times each value occurs in the data set.
How Can I Construct a Frequency Distribution?
To construct a frequency distribution:
- Organize the data
- Decide on the number of classes
- Calculate the class width
- Create class intervals
- Count the frequencies for each interval
- Create a frequency table
- Optionally, visualize the data with graphs like histograms or bar charts
What are Types of Frequency Distribution?
There are four types of frequency distributions that are as follows:
- Grouped Frequency Distribution
- Ungrouped Frequency Distribution
- Relative Frequency Distribution
- Cumulative Frequency Distribution
What is Ungrouped Frequency Distribution?
An ungrouped frequency distribution is a distribution that shows the frequency of each individual value in a data set.
What is Grouped Frequency Distribution?
A grouped frequency distribution is a distribution that shows the frequency of values within specified intervals or classes.
What is Frequency Count Distribution?
Frequency count distribution is a way of organizing and displaying data to show how often each unique value (or range of values) appears in a dataset
What is Relative Frequency Distribution?
A relative frequency distribution is a distribution that shows the proportion or percentage of values within each interval or class.
What is Cumulative Frequency Distribution?
A cumulative frequency distribution is a distribution that shows the number or proportion of values that fall below a certain value or interval.
Frequency Distribution – Table, Graphs, Formula
Frequency Distribution is a tool in statistics that helps us organize the data and also helps us reach meaningful conclusions. It tells us how often any specific values occur in the dataset.
A frequency distribution represents the pattern of how frequently each value of a variable appears in a dataset. It shows the number of occurrences for each possible value within the dataset.
Let’s learn about Frequency Distribution including its definition, graphs, solved examples, and frequency distribution table in detail.
