1. What is Relative Frequency?

Relative frequency is a statistical measure that shows how often something happens relative to the total number of observations. It's expressed as a proportion between 0 and 1.

2. How Does the Calculator Work?

The calculator uses the relative frequency formula:

Where:

• \( \text{Observed} \) — Number of times the event occurred
• \( \text{Total} \) — Total number of observations or trials

Explanation: The formula calculates the proportion of occurrences relative to all possible outcomes.

3. Importance of Relative Frequency

Details: Relative frequency is fundamental in probability and statistics, used to estimate probabilities, analyze distributions, and compare different data sets.

4. Using the Calculator

Tips: Enter the observed count (must be ≥0) and total count (must be >0 and ≥ observed count). The result will be between 0 and 1.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between frequency and relative frequency?
A: Frequency is the raw count, while relative frequency is the proportion compared to the total.

Q2: Can relative frequency be greater than 1?
A: No, it always ranges between 0 (never occurs) and 1 (always occurs).

Q3: How is relative frequency related to probability?
A: Relative frequency can estimate empirical probability when you have observational data.

Q4: What if my observed count is greater than total?
A: This is impossible - the calculator will not compute invalid inputs.

Q5: How precise are the results?
A: Results are rounded to 4 decimal places for readability while maintaining reasonable precision.
