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...

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...

Given an experimental situation, the student will write linear functions that provide a reasonable fit to data to estimate the solutions and make predictions.

A collection of lesson ideas, a practice activity, and teacher resources for exploring regression analysis.

In this activity students will measure various body parts looking for the golden ratio. The teacher will collect the various measurements from the calculators and send an augmented list to the students calculators. Students will then...

An analysis of how the volume of various jars impacts the burning time of candles. Data collected will be used to explore modeling, line fitting and linear regression Using graphing calculators.

An interactive program where students will explore regression lines. Students will be introduced to the correlation coefficient and come to understand what it represents through the given exploration. Requires Java.

Students will enjoy this data collection and class analysis experiment involving the time it takes for a hand squeeze to travel around a circle of people. From organizing the activity to collecting the data to making a table and graphing...

This activity is designed to give students the opportunity to estimate the least squares line given a set of points. The students are then able to check their "best fit" line by running a linear regression using the graphing calculator.

[Free Registration/Login may be required to access all resource tools.] Learn how to solve real-world problems using linear modeling.

The statistics resource explores scatter plots and correlation. Students learn about the concepts through notes and detailed examples. The resource consists of practice exercises to check for comprehension of the topics.

[Free Registration/Login may be required to access all resource tools.] This Concept introduces students to least-squares regression.

Using the LEGO MINDSTORMS NXT kit, students construct experiments to measure the time it takes a free falling body to travel a specified distance. Students use the touch sensor, rotational sensor, and the NXT brick to measure the time of...

[Free Registration/Login Required] This flipchart explores both linear models and scatter plots.

Investigate the relationship among humidity, air temperature, and the heat index while learning about modeling data, evaluating functions, and describing the end behavior of a function. Students will use graphing calculator technology to...

In this activity, students create lists of data points, plot them on a graph, and determine the regression equation of the best fitting line. They also understand exactly how the linear regression is determined.

Dozens of statistical terms are defined and illustrated in this glossary.

This paper surveys recent advances obtained for the two-dimensional bin packing problem, with special emphasis on exact algorithms and effective heuristic and metaheuristic approaches.
