Scatter Diagram - GCSE Psychology Definition

A scatter diagram, also known as a scatter plot, is a type of graph used to show the relationship between two different variables. In psychology, it helps us understand how one variable might be related to another by plotting data points on a grid. Each point represents a pair of values, one for each variable, and how they relate to each other. If the points create a pattern, like a line going up towards the right or the left, it suggests a relationship between the variables. For example, if study time increases and test scores increase, the points would allow a line to be drawn through them up to the right of the graph. Scatter diagrams are useful in psychology for visualising and interpreting data looking for a connection between variables.
