Scattered plots can display relationships between two pairs of continuous data. These graphs show symbols at the paired variables' data points' X and Y coordinates. Scattergrams and scatter charts are other names for scatterplots.
By looking at the dot pattern on a scatterplot, you may detect whether two continuous variables are correlated or related. The scatterplot shows the direction of any relationship and whether it is linear or curved if one exists. 1.) values on the X-axis of a continuous variable. When one of the variables may be categorized as an independent variable, this is typically the independent variable.
2.) Values on the Y-axis of a continuous variable are usually the dependent variable.
3.) Plotting of symbols at your data's (X, Y) coordinates. Represents various groups on the same graph; the graph can use various colored or shaped symbols.
