What is the formula for calculating the arithmetic mean?

The arithmetic mean formula is `Mean = (x₁ + x₂ + ... + xn) / n = Σx / n`.

When is the median a better measure of average than the mean?

The median is superior when datasets contain extreme outliers or skewed distributions (e.g., household incomes, home prices), as extreme values distort the mean but do not affect the median.

What is a weighted average and how is it calculated?

A weighted average assigns different levels of importance (weights) to values: `Weighted Average = Σ(Value × Weight) / Σ(Weight)`.

Can a dataset have multiple modes or no mode?

Yes. If two values tie for highest frequency, the dataset is bimodal. If all values appear with equal frequency, there is no mode.

What is the geometric mean?

The geometric mean is the nth root of the product of n positive numbers: `GM = (x₁ × x₂ × ... × xn)^(1/n)`, widely used for financial growth rates and investment returns.

What is the difference between mean, median, and mode in statistics?

Mean is the arithmetic average of all numbers; median is the middle value when sorted sequentially; mode is the most frequently occurring value in the dataset.

Numbers (comma, space or newline separated)

What Is the Difference Between Mean, Median, and Mode?

Mean is the arithmetic average (sum of all numbers divided by count). Median is the middle value when numbers are sorted in order (or average of the two middle numbers if count is even). Mode is the number that appears most frequently in the dataset.

Mathematical Formula & Equations

Calculates arithmetic mean, median, mode, range, and geometric mean for any dataset.

\[ \bar{x} = \frac{1}{n}\sum_{i=1}^n x_i, \quad \text{Median} = \text{Middle Value}, \quad \text{Mode} = \text{Most Frequent} \]

Calculation Example

For dataset [4, 8, 6, 5, 3, 8, 9]: Mean = 6.14, Median = 6, Mode = 8, Range = 6.
