A scatter plot is a type of graph that displays values for two different variables as points on a two-dimensional grid. Each point represents an observation, with one variable plotted along the x-axis and the other along the y-axis. This visual representation helps to identify relationships or patterns between the two variables, such as correlation. Scatter plots are commonly used in statistics and data analysis to illustrate trends, clusters, or outliers in data sets. For example, researchers might use a scatter plot to analyze the relationship between study hours and test scores among students, helping to visualize how one variable may affect the other.
