1. What is the Average Score?

The average (or arithmetic mean) is calculated by summing all the scores and dividing by the number of scores. It provides a central value that represents a set of numbers.

2. How Does the Calculator Work?

The calculator uses the average formula:

Where:

• \( \sum \text{scores} \) — Sum of all score values
• \( n \) — Number of scores

Explanation: The equation calculates the central tendency of a data set by equally distributing the total sum across all values.

3. Importance of Average Calculation

Details: The average is a fundamental statistical measure used to summarize data, compare groups, and make informed decisions in various fields.

4. Using the Calculator

Tips: Enter numerical scores separated by commas. The calculator will ignore any non-numeric values and calculate the average of valid numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between average and median?
A: Average is the sum divided by count, while median is the middle value. Average is affected by outliers, while median is more robust to extreme values.

Q2: Can I calculate average with negative numbers?
A: Yes, the calculator handles negative numbers in the same way as positive numbers.

Q3: How many decimal places does the calculator show?
A: The result is rounded to 2 decimal places for readability.

Q4: What if I enter non-numeric values?
A: Non-numeric values will be ignored in the calculation, and only valid numbers will be used.

Q5: Is there a limit to how many scores I can enter?
A: No strict limit, but extremely large lists may take longer to process.
