What is descriptive statistics?

It's the set of techniques for summarizing and describing data sets. It includes measures of central tendency (where data centers) and dispersion (how data distributes).

Main measures

Central tendency: mean, median, mode. Dispersion: range, variance, standard deviation. Position: quartiles, percentiles. Each measure reveals different aspects of the data.

Box plot interpretation

The box shows the interquartile range (IQR) where the central 50% of data lies. The inner line is the median. Whiskers show the range without outliers.
