C2Formal / Technical / Academic
Definition
Meaning
Numerical and graphical summaries used to describe the basic features and patterns within a dataset.
The branch of statistics focused on quantitatively summarizing and presenting the characteristics of collected data, without making inferences or generalizations beyond the data at hand. It organizes raw data into understandable information through measures of central tendency, dispersion, and graphical representations.
Linguistics

Frequently Asked Questions
It is usually treated as plural when referring to specific summary numbers ('The descriptive statistics are in Table 1'), but can be singular when referring to the field or practice ('Descriptive statistics is a fundamental topic').
Descriptive statistics summarise data you have (your sample), while inferential statistics use that sample data to make predictions or inferences about a larger population.
Measures of central tendency (mean, median, mode), measures of dispersion (range, variance, standard deviation), and measures of shape (skewness, kurtosis), along with graphical summaries like histograms and box plots.
No. Descriptive statistics can show patterns and summaries within your data, but they cannot, by themselves, prove a hypothesis or establish causality. That requires inferential statistical testing.
