Progress Check
Use this activity to assess whether you can
Use a scatterplot to display the relationship between two quantitative variables.
For a linear relationship, use the least squares regression line to model the pattern in the data.
Use the correlation coefficient and the standard error to determine whether the least squares regression model is a good fit.
Variables for ALL Data Sets
Explanatory Variable: Age Response Variable: IAT Score
Prompt
For the explanatory variable Age and the response variable IAT Score, use StatCrunch to graph the scatterplot with its regression line and produce the regression equation with r-squared and the standard error - all at the same time.
You should see page 1 of 2 of the StatCrunch output window. Copy all information above the Parameter estimates: table (do not copy the tables). Paste the information into your response.
