1. What is Average?

The average (mean) is a measure of central tendency calculated by summing all values in a dataset and dividing by the number of values. It provides a single value representing the center of the data.

2. How Does the Calculator Work?

The calculator uses the average formula:

Where:

• \( x_i \) — Individual values in the dataset
• \( n \) — Total number of values
• \( \sum \) — Summation of all values

Explanation: The calculator sums all valid numbers you enter and divides by the count of numbers.

3. Importance of Average Calculation

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

4. Using the Calculator

Tips: Enter numbers separated by commas (e.g., 85, 90, 78). The calculator will ignore any non-numeric values. At least one valid number is required.

5. Frequently Asked Questions (FAQ)
