1. What is the Average?

The average (mean) is a measure of central tendency calculated by summing all values and dividing by the count of values. It represents the central value of a dataset.

2. How Does the Calculator Work?

The calculator uses the average formula:

Where:

• \( \sum \text{scores} \) — Sum of all numerical values
• \( \text{count} \) — Number of values

Explanation: The equation calculates the arithmetic mean by dividing the total sum by the number of values.

3. Importance of Average Calculation

Details: Averages are fundamental in statistics, used to summarize data, compare groups, and make decisions in fields like education, business, and research.

4. Using the Calculator

Tips: Enter numerical values separated by commas (e.g., 85,90,78,92). The calculator will ignore any non-numeric values in the input.

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 when numbers are ordered. Median is less affected by outliers.

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

Q3: What if I enter non-numeric values?
A: The calculator will automatically filter out any non-numeric values before calculation.

Q4: How many decimal places does the calculator show?
A: Results are rounded to 2 decimal places for readability.

Q5: Can I calculate weighted averages with this?
A: No, this calculates simple arithmetic mean. For weighted averages, each value would need its own weight parameter.
