Scatter Diagrams: Visualizing Relationships Between Variables

Scatter diagrams are graphs that plot two variables against each other to identify patterns or relationships.
They help businesses visualize how changes in one variable might affect another.

Example

A company might use a scatter diagram to see if there's a relationship between advertising spend and sales revenue.

Active recall

Tip

Can you tell what's missing from the diagram?
Be sure to always label your axes clearly depending on your data set to ensure the data is easy to interpret.

Line of Best Fit: Identifying Trends

The line of best fit is a straight line drawn through the data points on a scatter diagram.
It summarizes the relationship between the variables and helps identify trends.

Example

If a scatter diagram shows a positive relationship between advertising spend and sales, the line of best fit will slope upwards.

How to Draw a Line of Best Fit

Balance the Line: Ensure the line has roughly equal numbers of points above and below it.
