• Testing a hypothesis by displaying a scatterplot of experimental data, determining the regression coefficient and equation, and determining the correlation coefficient
   

Real Population Data
Students investigate real population data and plot them using the TI graphing calculator. Several activities are included as well as instructions on how to use the calculator to plot data.

What’s the [intersection] Point?
This unit introduces students to technology as a means of graphing linear equations on a graphing calculator and finding the point of intersection and inputting data into lists.

Windspeed vs. Temperature
In this activity, students will create their own anemometer, an instrument used to measure wind speed. Using this tool and the Beaufort Scale, students will measure and record estimated and average wind speeds. As an extension, students can plot and then analyze real-world wind speed data collected by Pathfinder during one of its recent missions

Chicago Public Schools
The lessons for days 166 to 168 deal with scattergrams and related topics.

Scatterplot Guessing Game
This is a game that displays random scatterplots. Students match 4 of them to their correlation coefficient.

Scatterplots
Interactive lessons on midpoint and distance on the Cartesian coordinate plane, including a java applet that does scatterplots and linear regressions.           

QELP
This website is full of different data sets, including linear sets. The data is very clean and easy to use. Download data sets in Excel or Minitab format and add regressions using Excel or use the data for calculator activities.

A Functional Housing Market
Students will access the Internet to search for housing prices in Houston, Texas (the location can be changed to accommodate any location) and compare the prices to the number of square feet.

QELP
This is the best set of data sets in the world. Download data sets in Excel or Minitab format and add regressions using Excel or use the data for calculator activities.

Online Data Site
Great data sets that range from linear to logistic.
