1. What is Mean?

The mean (or average) is a measure of central tendency that represents the sum of all values divided by the number of values. It's one of the most fundamental concepts in statistics and data analysis.

2. How Does the Calculator Work?

The calculator uses the mean formula:

Where:

• \( x_i \) — Individual data points
• \( n \) — Total number of data points
• \( \sum \) — Summation symbol

Explanation: The calculator sums all the numbers you provide and divides by the count of numbers to find the average.

3. Importance of Mean Calculation

Details: The mean provides a single value that represents the center of a data set. It's widely used in statistics, research, business analytics, and everyday life to understand data distributions.

4. Using the Calculator

Tips: Enter numbers separated by commas (e.g., 5, 8, 12, 3). The calculator will ignore any non-numeric values. For decimal numbers, use point notation (e.g., 3.14).

5. Frequently Asked Questions (FAQ)

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

Q2: When shouldn't I use the mean?
A: Avoid using mean for skewed distributions or when outliers are present, as it may not represent the data well.

Q3: Can I calculate mean for negative numbers?
A: Yes, the mean works for any real numbers, positive or negative.

Q4: What if I enter only one number?
A: The mean of a single number is the number itself.

Q5: How precise is the calculator?
A: Results are rounded to 4 decimal places for clarity.
