Key Concepts

Probability

Probability is the measure of how likely an event is to occur, typically expressed as a number between 0 and 1. It involves analyzing a situation or experiment and quantifying the chance of a specific outcome based on available data or theoretical models.

Relative Frequency

Relative frequency is the method of determining probability by dividing the number of times an event occurs by the total number of observations or trials. It is used as an empirical estimate of the probability, particularly when data is gathered from surveys or experiments.

Frequency Distribution

A frequency distribution is a summary of how often different outcomes or categories occur within a set of data. In survey settings, it organizes data into intervals or categories, allowing for easy computation of probabilities, such as determining the chance that a value falls within a specific range.
