Scatter Diagrams
Muhtasari
A scatter diagram plots pairs of values to reveal whether two quantities are connected, and a line of best fit lets you make predictions. The international course adds the power of a graphic calculator to find the line of best fit precisely.
In this lesson you will draw and interpret scatter diagrams, describe correlation, draw and use a line of best fit, and (at Extended) use a graphic display calculator to find the equation of linear regression.
Malengo
- 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.
- Use a graphic display calculator to find and use the equation of linear regression. (Extended only)
