When to use each measure
Mean: Best when data is roughly symmetrical with no extreme outliers. Good for test scores, temperatures.
Median: Best when data has outliers or is skewed. Better for house prices, incomes where a few very high values distort the mean.
Mode: Best for categorical data or when you need the most common value. Used in fashion sizes, most popular products.
Standard deviation: Measures how spread out the data is. Low = data clustered near the mean. High = data widely spread.
