- Correlation and Line of Best Fit
The purpose of this task sheet is to explore the relationship between the pattern of the points in a scatter plot, the correlation coefficient, line of best fit, outliers, the point (Mean of x s, Mean of y s) and the numbers of points in each quadrant.
Instructions:
- Use the GeoGebra file in conjunction with the student activity.
- Click on the mini boxes to identify the label on the GeoGebra file.
Note:
Calculating the point (Mean of x s, Mean of y s) and using it to split the plane into 4 quadrants is not specifically mentioned in the syllabus. However, it is a helpful way of learning about relationships in the data.
