Statistics Calculator
Descriptive statistics summarize and describe the key features of a dataset: central tendency (mean, median, mode), spread (range, variance, standard deviation), and shape (skewness, kurtosis). They condense large datasets into interpretable summaries.
💡
Pro Tip
For skewed data (like incomes, house prices), the median is a better measure of central tendency than the mean. Use mean when data is approximately normally distributed.

Did You Know?
Average salary statistics are often misleading because mean income is higher than median income due to a small number of very high earners. The median better represents "typical" income — in the US, median household income is about $75k while mean is $100k+.
