Week 14: November 9-13

Benchmark Review & Discussion #15-16

Topic 4-2: “Analyze Linear Associations”

• Standard 

1. 8.SP.A.2:  Know that straight lines are widely used to model linear relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line and informally assess the model fit by judging the closeness of the data points to the line.

2. 8.F.A.3:  Know and interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.

3. 8.F.B.4:  Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models and in terms of its graph or a table of values.

• Objective

1. Recognize whether the paired data has a linear association, a nonlinear association, or no association

2. Draw a trend line to determine whether a linear association is positive or negative and strong or weak

• Essential Understanding

1. A trend line on a scatter plot approximates the linear association between the paired data.  Scatter plots can show a linear or nonlinear association, or no association.

• Essential Question: How does a scatter plot show the relationship between paired data?
