Guide: Mean, Median, and Mode
The arithmetic mean is the most commonly used measure of central tendency, calculated by summing all values and dividing by their count. It works best for data that is symmetrically distributed without extreme outliers. When data clusters around the mean, it provides a complete picture of the typical value.
The median is the value that divides the dataset into two equal halves - half the values are smaller, half are larger than the median. It is resistant to outliers, making it ideal for data with extreme values or skewed distributions. It is commonly used for income, real estate prices, and other economic data.
The mode is the most frequently occurring value in a dataset. It is useful for identifying the most popular category or option. When all values are unique, there is no mode - this is called a unimodal distribution.
When to use which: Use the mean for symmetric data without outliers. Use the median for skewed data or data with extreme values. Use the mode for categorical data or when you want to know the most common response.
