Scatter plots are also called scatter graphs, scatter charts, scattergrams, and scatter diagrams. They use a Cartesian coordinates system to display values of typically two variables for a set of data.
When should we use a scatter plot? Scatter plots can be constructed in the following two situations:
- When one continuous variable is dependent on another variable, which is under the control of the observer
- When both continuous variables are independent
There are two important concepts—independent variable and dependent variable. In statistical modeling or mathematical modeling, the values of dependent variables rely on the values of independent variables. The dependent variable is the outcome variable being studied. The independent variables are also referred to as regressors. The takeaway message here is that scatter plots are used when we need to show the...
