Relative Frequency Calculator

This is free Relative frequency calculator displays a table that describes how many times given values occur relative to all the observations in the dataset.

The frequency distribution calculator also spits out the number of other descriptors of given data. So, if you wonder how exactly it works and displays a frequency distribution table, then dive right in and find out!

What is Relative Frequency?

In mathematics, the relative frequency of events is defined as the ratio of the number of successful tests to the total number of tests performed. Relative frequency is simply the number of times something happened divided by the number of all attempts. The relative frequency distribution must be in the percentage.

Since this is experimental, different relative frequencies can be obtained by repeating the experiment. To calculate the frequency, we need to calculate:

• Calculate the frequency of the entire population
• Calculate the frequency of a subgroup of the population

Relative Frequency Formula:

Relative frequency is a comparison of the digital repetition frequency and the total frequency of all numbers. From a mathematical point of view, the relative frequency is the individual frequency of the element divided by the total number of repetitions that occur.

The calculation formula of relative frequency distribution is as follows:

Relative Frequency = f / n

Here,

n = total frequencies

f = number of times the data occurred in one observation

Lastly, the frequency table calculator displays a column chart of Input Values:

Cumulative Relative Frequency:

Cumulative relative frequency is the accumulation of previous relative frequencies. To get this, add all previous relative frequencies to the current relative frequency. The last value is equal to the sum of all observations. Because all the previous frequencies have been added to the previous sum.

How does Relative Frequency Calculator Work?

The frequency distribution calculator determines the relative frequency for individuals and groups separately by following these guidelines:

Input:

• First, enter the data set for relative frequency distribution, separated with comma (,).
• Now, choose the individual or group frequency according to requirements.
• Hit the calculate button for relative frequency.

Output:

If you select Individual Frequency, then it shows

• Table for cumulative, relative, and cumulative relative frequency for the given data set individually with graph.
• It also shows the sorted data set, Mean, Median, Mode, Range, Sum of square, Variance, etc.

If you choose Group Frequency, then the relative frequency calculator provides:

• Frequency table with the different number of groups.
• Statistical characteristics and column chart for input group values.
