Describing Bivariate Data

In these lessons, students investigate the relationship between two quantitative variables by analyzing scatterplots, outliers and influential points, correlation coefficients, and the least-squares regression line. Students create and describe graphs and identify and use the important characteristics of the graphs to better understand the relationship between the variables.

Statistics: Describing Bivariate Data Activities

Title
Scatterplot Pulse Rates This lesson involves creating a scatterplot and fitting a line to student pulse rates collected before and after exercise. Standards \| Textbook	3461	13
Monopoly and Regression This lesson involves analyzing the association between the number of spaces from Go and the cost of the property on a standard Monopoly board. Standards \| Textbook	3532	16
Tootsie Pops & Hand Span Students will collect data, find the linear regression model of the data, and address aspects of the data that affect regression. Standards \| Textbook	3929	11
Investigating Correlation This lesson involves investigating the connection between the scatterplot of bivariate data and the numerical value of the correlation coefficient. Standards \| Textbook	3829	12
Interpreting R² This lesson involves predicting values of a particular variable. Standards \| Textbook	3331	12
Influencing Regression This lesson involves a least-squares regression line fit to a set of nine values. Standards \| Textbook	3487	12
Influence and Outliers In this activity, students will identify outliers that are influential with respect to the least-squares regression line. Students will describe the role of the location of a point relative to the other data in determining whether that point has influence on the least-squares regression line. Standards \| Textbook	4060	14
Transforming Bivariate Data This lesson involves square root, semi-log, and log-log transformations of curved bivariate data using given data sets. Standards \| Textbook	3333	12
