U7 Correction Session

I can

construct a scatterplot.
identify different types of association for bivariate data.
construct trend lines.
identify clusters.
identify outliers.

Construct a scatterplot of the following points (2,5), (4,7), (9, 4) and (12, 15).

Positive Linear Association

Negative Linear Association

Nonlinear - No Association

Nonlinear

Clusters: A group of points that are close together. (In green)
Outliers: A point that is located away from the majority of the points. (Red point)

Clusters and Outliers

• Trend lines show the trend!

• Right in the middle of all of the points

• Do not have to touch/go through any points

• Should be one straight line
