Statistics and Probability - Key Concepts

Descriptive statistics and probability distributions


Statistics and Probability are two closely related branches of mathematics that deal with data and uncertainty. Statistics is the study of data: how to collect, summarize, interpret, and analyze it. Probability, on the other hand, provides the theoretical foundation to model uncertainty and make predictions or decisions based on data.

Basic Concepts in Statistics

Descriptive Statistics

This involves summarizing and interpreting data through measures like mean, median, and mode.

Inferential Statistics

This goes beyond the data at hand to make predictions or inferences about a population based on a sample.

Probability Theory

Random Experiment

An action or process that leads to one of several possible outcomes, each with a certain likelihood.

Probability Distribution

A function that describes the likelihood of obtaining the possible outcomes in an experiment.
