Bar Chart - GCSE Psychology Definition

A bar chart is a graphical representation used to display and compare the frequency, count, or percentage of different categories of data, often used in GCSE Psychology to illustrate and analyse research findings or experimental results. Each bar represents a category of data, with the length or height of the bar corresponding to the value it represents, allowing for quick visual comparison. Typically, the categories are placed along the horizontal axis, while the vertical axis represents the numerical value, making it easy to identify trends, patterns, or outliers in psychological data sets. Bar charts are particularly useful when dealing with discrete data and can effectively communicate how variables differ across distinct groups or conditions in psychological studies.
