Within quantitative data, we further classify numbers into discrete counts and continuous measurements, a distinction that dictates which statistical methods are appropriate. It quantifies the likelihood of an event occurring, expressed as a number between 0 (impossible) and 1 (certain).

The most common measure of central tendency is the mean, or average, but the median (the middle value) and mode (the most frequent value) are equally important, especially when dealing with skewed distributions or outliers. Qualitative data describes qualities or characteristics, such as colors or opinions, while quantitative data involves numerical values that can be measured or counted.
This begins with distinguishing between different types of data, primarily qualitative and quantitative. At its core, statistics is the science of collecting, organizing, and interpreting data to turn raw numbers into meaningful information.

Measures of Spread To understand how much variation exists in the data, we rely on measures of spread or dispersion. However, the most informative measure is usually the standard deviation, which calculates how far data points typically deviate from the mean.
