1. What Is Relative Frequency?

Relative frequency is a statistical measure that shows the proportion or percentage of times a particular value occurs in a dataset relative to the total number of observations. It provides a normalized way to understand the distribution of data.

2. How Is Relative Frequency Calculated?

The relative frequency is calculated using the formula:

\[ \text{Relative Frequency} = \frac{\text{Frequency}}{\text{Total}} \]

Where:

\( \text{Frequency} \) — The number of times a specific value occurs in the dataset
\( \text{Total} \) — The total number of observations in the dataset

Explanation: This calculation converts raw frequency counts into proportions that sum to 1 (or percentages that sum to 100%), making it easier to compare distributions across different sample sizes.

3. Importance Of Relative Frequency

Details: Relative frequency is essential for creating frequency distributions, calculating probabilities, comparing datasets of different sizes, and understanding the underlying patterns in categorical data. It forms the basis for probability distributions and statistical analysis.

4. Using The Calculator

Tips: Enter the frequency (count of specific occurrences) and total (overall count of observations). Both values must be positive numbers, and frequency cannot exceed total. The calculator provides results as both decimal proportion and percentage.

5. Frequently Asked Questions (FAQ)

Q1: What Is The Difference Between Frequency And Relative Frequency?
A: Frequency is the raw count of occurrences, while relative frequency is the proportion or percentage of those occurrences relative to the total observations.

Q2: How Do You Convert Relative Frequency To Percentage?
A: Multiply the relative frequency (as a decimal) by 100. For example, a relative frequency of 0.25 equals 25%.

Q3: What Is The Sum Of All Relative Frequencies In A Dataset?
A: The sum of all relative frequencies in a complete dataset should equal 1 (or 100% when expressed as percentages).

Q4: When Should I Use Relative Frequency Instead Of Absolute Frequency?
A: Use relative frequency when comparing distributions across different sample sizes or when you need to understand proportions and probabilities rather than raw counts.

Q5: Can Relative Frequency Be Greater Than 1?
A: No, relative frequency represents a proportion and should always be between 0 and 1 (or 0% to 100%).
