This site features an online textbook with very in-depth information about multivariable statistics. (NOTE: In the archived version, some images do not appear. However, many of them are multiple-choice questions for students, and if you...

Students examine the USA TODAY Snapshot "More of U.S.", construct a graph from the data, produce a mathematical model (linear) for the data, determine the rate of change for the data, and make predictions about future population levels.

This task asks students to identify when two quantitative variables show evidence of a linear association and to describe the strength and direction of that association. Students will use a scatterplot showing the finishing times for the...

Learners use a scatter plot to determine whether data can be modeled by a linear function, a quadratic function, a trigonometric function, or that there appears to be no relationship between x and y. The resource consists of an enlarged...

[Free Registration/Login Required] A basic premise of science is that much of the physical world can be described mathematically and many physical phenomena are predictable. This scientific outlook took place in Europe during the late...

In this activity, students take distance readings as they walk in front of a CBR. They apply the properties of a linear function to develop a model for the motion and interpret the values used in the model. Students learn to graph...

This activity is designed to help students work with linear regression models, error, correlation coefficients and coefficients of determination. In this activity students not only deal with the mathematical concepts of regression but...

In this activity, students create a situation that produces linear behavior by stepping heel to toe and taking distance readings as each step is taken. Students then apply the properties of a linear function to develop a model for motion.

Students use a temperature probe to collect data as the warmed probe cools. Students investigate Newton's law of cooling and model cooling data with an exponential function. They fit the data to a mathematical model after analysis.

Students will explore linear & quadratic functions to determine how they model the relationship between air temperature & heat index. Once the models are determined students will make predictions about heat index when given a...

Students are shown two tables of data showing the approximate boiling point of water at different elevations. Both data sets can be modeled by linear functions but with different slopes. When the tables are combined, however, students...

This task asks students to analyze a set of data about the height of a basketball for each time it bounces. They choose a model that reasonably fits the data and use the model to answer questions about the physical context. This variant...

For this task, students are asked to find a linear function which models the number of households in the U.S. as a function of the year. They are also to construct and use an inverse function to model the context, and interpret their...

In this activity, students collect information about the stops made, time taken, and distance covered by a train on one of Amtrak's routes. They find a mathematical model that can best track the train. Students understand concepts...

In this activity, students explore linear equation models for real-life situations. They learn to find a linear equation when two pairs of related points are on a line.

In this activity, students examine quantities that are linearly related and can be visually represented using a straight-line graph. Students collect distance versus time data using a motion detector and find a model for the...

In this activity, students' will use a motion detector to collect position data showing evenly-spaced jumps in value. They will then model this data using the greatest integer function.

In this activity, students use linear functions to model and solve problems in situations with slope and a constant rate of change. They learn to represent situations with variables in expressions, equations, and inequalities and use...
