1. What is the Mean of a Normal Distribution?

The mean (μ) of a normal distribution is the central value around which the data is symmetrically distributed. It determines the location of the center of the bell curve.

2. How Does the Calculator Work?

The calculator uses the formula for arithmetic mean:

\[ \mu = \frac{1}{n}\sum_{i=1}^{n} x_i \]

Where:

\( \mu \) — Mean of the distribution
\( n \) — Number of data points
\( x_i \) — Individual data points

3. Importance of Mean Calculation

Details: The mean is a fundamental measure of central tendency in statistics. In normal distributions, it's one of the two parameters (along with standard deviation) that completely define the distribution.

4. Using the Calculator

Tips: Enter numerical values separated by commas. The calculator will ignore any non-numeric values in the input.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between mean and median?
A: Mean is the average value, while median is the middle value. In normal distributions, they are equal.

Q2: How does mean affect the normal distribution curve?
A: The mean determines where the center of the bell curve is located on the x-axis.

Q3: Is the mean always the best measure of central tendency?
A: For normal distributions, yes. For skewed distributions, median might be more representative.

Q4: Can I calculate mean for non-normal distributions?
A: Yes, the mean can be calculated for any numeric dataset, though its interpretation may differ.

Q5: What if my data has outliers?
A: Outliers can significantly affect the mean. Consider examining your data distribution first.
