A scatterplot is a graph used to visually represent the relationship between two quantitative variables. Each data point corresponds to a pair of values, with one variable placed along the horizontal axis (x-axis) and the other along the vertical axis (y-axis). The overall pattern of the points helps in determining if the relationship between the two variables is linear, nonlinear, or absent.
A linear relationship means that the data points tend to follow an approximate straight-line pattern. This can either slope upward or downward. By interpreting the direction and clustering of points, one can determine whether the relationship is positive, negative, or weak. Scatterplots are commonly used in education, business, health, and scientific research to detect trends and predict outcomes.
