Graph regression line on scatter plot

WebA scatter graph is drawn using the following steps: Step 1: Decide on the two variables that you will be comparing. Step 2: Collect and tabulate data for these variables. The x / independent variable will be tabulated in the second row and your y / dependent variables will be in the third. Step 3: Use your collected data to plot the points. WebWhat is a scatter plot. A scatter plot (or scatter diagram) is a two-dimensional graphical representation of a set of data. Each x/y variable is represented on the graph as a dot or a cross. This type of chart can be used in to visually describe relationships ( correlation) between two numerical parameters or to represent distributions.
