1. What is Relative Frequency?

Relative frequency is a statistical measure that shows how often something happens relative to the total number of occurrences. For grades, it represents the proportion of students who received a particular grade compared to the entire class.

2. How Does the Calculator Work?

The calculator uses the relative frequency formula:

Where:

• Grade Count — Number of students receiving a particular grade
• Total Students — Total number of students in the class

Explanation: The formula calculates what fraction of the total students received a specific grade.

3. Importance of Relative Frequency

Details: Relative frequency helps educators understand grade distributions, identify potential issues in grading, and compare performance across different classes or years.

4. Using the Calculator

Tips: Enter the count of students who received a particular grade and the total number of students in the class. Both values must be positive integers, and grade count cannot exceed total students.

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: What are typical relative frequency values?
A: Values range from 0 to 1, where 0 means no students received the grade and 1 means all students received it.

Q3: Can relative frequency be expressed as a percentage?
A: Yes, multiply by 100 to convert to a percentage (e.g., 0.25 = 25%).

Q4: Why use relative frequency instead of absolute counts?
A: Relative frequency allows comparison between classes of different sizes.

Q5: How precise should relative frequency be?
A: Typically reported to 2-4 decimal places depending on class size and required precision.
