Topic 4  Investigate Bivariate Data
Standard: MAFS.8.SP.A  Investigate patterns of associations in bivariate data.
41: Construct and Interpret Scatter Plots
Objectives:
 I can construct a scatter plot graph to model paired data.
 I can utilize a scatter plot to identify and interpret the relationship between paired data.
 How does a scatter plot show the relationship between paired data?
 cluster
 gap
 measurement
 data
 negative association
 outlier
 positive association

42: Analyze Linear Associations
Objectives:
 I can recognize whether the paired data has a linear association, a nonlinear association, or no association.
 I can draw a trend line to determine whether a linear association is positive or negative and a strong or weak.
 How can you describe the relationship between the two sets of data?
 trend line
43: Use Linear Models to Make Predictions
Objectives:
 I can use the slope and yintercept of a trend line to make a prediction.
 I can make a prediction when no equation is given by drawing trend lines and writing the equation of the linear model.
 How do linear models help you to make a prediction?
 none
44: Interpret TwoWay Frequency Tables
Objectives:
 I can organize paired categorical data into a twoway frequency table.
 I can compare and make conjectures about data displayed in a twoway frequency table.
 How does a twoway frequency table show the relationship between sets of paired categorical data?
 categorical data
45: Interpret TwoWays Relative Frequency Tables
Objectives:
 I can construct twoway frequency tables and twoway relative frequency tables.
 I can compare and make conjectures about data displayed in a twoway relative frequency table.
 What is the advantage of a twoway relative frequency table for showing relationships between sets of paired data?
 relative frequency table
