Construct scatter plots

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

Draw

Construct a scatterplot of the following points: (1, 12), (3, 8), (5, 6), and (8, 2).

Types of Association

Negative Linear Association

Nonlinear - No Association

Nonlinear

Multiple Choice

Identify the association of this scatterplot.

• Positive linear association

• Negative linear association

• No association

• Non-linear association

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

Draw

1. Circle the cluster in the graph.

Put an X on the outlier.

Drawing Trend Lines

• 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

Multiple Choice

Which line is the best trend line for this scatterplot?

• Red line

• Purple line

• Green line
