Topic 4 - Investigate Bivariate Data
Standard: MAFS.8.SP.A - Investigate patterns of associations in bivariate data.
4-1: Construct and Interpret Scatter Plots
- 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?
- negative association
- positive association
- scatter plot
4-2: Analyze Linear Associations
- 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
4-3: Use Linear Models to Make Predictions
- I can use the slope and y-intercept 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?
4-4: Interpret Two-Way Frequency Tables
- I can organize paired categorical data into a two-way frequency table.
- I can compare and make conjectures about data displayed in a two-way frequency table.
- How does a two-way frequency table show the relationship between sets of paired categorical data?
- categorical data
4-5: Interpret Two-Ways Relative Frequency Tables
- I can construct two-way frequency tables and two-way relative frequency tables.
- I can compare and make conjectures about data displayed in a two-way relative frequency table.
- What is the advantage of a two-way relative frequency table for showing relationships between sets of paired data?
- relative frequency table
