Scatter Diagrams
Gbogbo ọrọ náà
A scatter diagram plots pairs of values to reveal whether two quantities are connected. Does more study time go with higher scores? Does temperature affect sales? The pattern of the points answers the question, and a line of best fit lets you make predictions.
In this lesson you will draw and interpret scatter diagrams, describe correlation as positive, negative or zero, and draw and use a line of best fit.
Ebumnobi
- Draw and interpret scatter diagrams.
- Understand what is meant by positive, negative and zero correlation.
- Draw by eye, interpret and use a straight line of best fit.

Scatter Plots
Before we take up the discussion of linear regression and correlation, we need to examine a way to display the relation between two variables x and y . The most common and easiest way is a scatter plot . The following example illustrates a scatter plot. In Europe and Asia, m-commerce is popular. M-c
