1. What is a Normalized Marks Calculator?

Definition: This calculator converts raw marks to a normalized scale (0-100%) based on the class's minimum and maximum marks.

Purpose: It helps educators and students compare performance across different tests or classes by standardizing the grading scale.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ M_n = \frac{(M - M_{min})}{(M_{max} - M_{min})} \times 100 \]

Where:

\( M_n \) — Normalized marks (%)
\( M \) — Raw marks (dimensionless)
\( M_{min} \) — Minimum marks in class (dimensionless)
\( M_{max} \) — Maximum marks in class (dimensionless)

Explanation: The formula scales the raw marks relative to the class range, with the lowest score becoming 0% and the highest becoming 100%.

3. Importance of Normalized Marks

Details: Normalization allows fair comparison of performance across different tests with varying difficulty levels or grading scales.

4. Using the Calculator

Tips: Enter the student's raw marks, the minimum marks in the class, and the maximum marks in the class. Maximum must be greater than minimum.

5. Frequently Asked Questions (FAQ)

Q1: Why normalize marks?
A: Normalization accounts for test difficulty variations and creates a standardized scale for comparison.

Q2: What does 0% normalized mean?
A: It means the student scored equal to the minimum marks in the class.

Q3: What does 100% normalized mean?
A: It means the student scored equal to the maximum marks in the class.

Q4: Can normalized marks exceed 100%?
A: No, the formula caps at 100%. If raw marks exceed maximum, it should be treated as 100%.

Q5: How is this different from grading on a curve?
A: Normalization is a linear transformation, while curving typically involves statistical distributions.
