Relative Frequency Formula:
From: | To: |
Relative frequency is the fraction or proportion of times a value occurs in a dataset compared to the total number of observations. It's a fundamental concept in statistics for understanding probability distributions.
The calculator uses the relative frequency formula:
Where:
Explanation: The formula divides the count of a specific outcome by the total count of all possible outcomes, giving a proportion between 0 and 1.
Details: Relative frequency is essential for probability estimation, statistical analysis, and data visualization. It allows comparison between datasets of different sizes and forms the basis for empirical probability.
Tips: Enter the frequency count of your specific event and the total count of all events. Both values must be positive numbers, with total > 0.
Q1: What's the difference between frequency and relative frequency?
A: Frequency is the raw count, while relative frequency is the proportion (frequency divided by total count).
Q2: What are possible values for relative frequency?
A: It ranges from 0 (never occurs) to 1 (always occurs), often expressed as a percentage (0% to 100%).
Q3: How is relative frequency related to probability?
A: Relative frequency from empirical data approximates theoretical probability as sample size increases.
Q4: Can relative frequency be greater than 1?
A: No, since frequency can't exceed the total count, relative frequency is always ≤1.
Q5: How is relative frequency used in histograms?
A: Histograms can display relative frequencies on the y-axis to show proportion rather than raw counts.
