Histogram - English Definition & Meaning

Definition

A histogram is a graphical representation of the distribution of numerical data. It uses bars to show the frequency of data falling within certain intervals or bins. Unlike a bar chart, a histogram shows the distribution of a continuous variable. Think of it as a visual frequency counter. Histograms are used to analyze data patterns, identify outliers, and understand the underlying distribution of a dataset. 📊

Etymology

The term 'histogram' is relatively modern, coined by Karl Pearson in the late 19th century. Its etymology is uncertain, but it likely combines 'histo-' (related to 'history' or 'tissue,' referring to the collection of data) with '-gram' (meaning 'drawing' or 'record'). It reflects the idea of visually representing the 'history' or distribution of a dataset.
