See the New HTML5 Simulation Pages Now LIVE!

New HTML5 Page

We are excited to now have individual HTML5 sim pages where you can easily access sample learning goals (under About), Teacher Tips and Activities (under For Teachers), Related Simulations, and Software Requirements. With the new pulldown menus, everything about the simulation is on a single screen. There’s also a link to conveniently access the corresponding original JAVA/Flash sims and their translations.

And don’t forget to help bring more improvements and HTML5 sims by donating at:

New #HTML5 Least-Squares Regression Simulation

Least-Squares Regression

In the new #HTML5 Least-Squares Regression simulation, students can flexibly explore ideas related to correlation, best-fit lines, residuals, and outliers. Build a data set or use real-world data to discover the meaning of a correlation coefficient and determine when a linear fit is reasonable.

Least-Squares Regression is appropriate for any grade level that is studying scatter plots, best-fit lines, regression, or correlation, and is specifically aligned with Common Core State Standards in high-school mathematics.
