Statistics and probability

the branch of mathematics that deals with collecting, analyzing, interpreting, presenting, and organizing data. It helps us understand patterns, trends, and relationships within data to make informed decisions. It involves techniques like probability, hypothesis testing, regression analysis, and descriptive statistics, among others.

It refers to methods for summarizing and describing the main features of a data set. It helps present data in a simple and understandable way. Some common tools in descriptive statistics

It goes beyond summarizing the data. It uses sample data to make generalizations or predictions about a larger population.

a branch of mathematics that deals with the likelihood or chance of different outcomes occurring. It quantifies uncertainty and is used to predict the likelihood of events

a type of probability that applies to situations where all possible outcomes are equally likely. It is often used in games of chance or experiments with a finite number of equally probable outcomes

also known as experimental probability, is based on observing actual experiments or past data to estimate the probability of an event. Unlike classical probability, which assumes all outcomes are equally likely, empirical probability is calculated from the frequency of events occurring in practice.

A type of probability that is based on personal judgment, intuition, experience, or beliefs rather than on empirical data or mathematical calculations. It reflects an individual's confidence in the occurrence of an event, often in the absence of complete data or objective evidence.
