Interaction! - Windows software for graphing statistical interactions

Interaction is now free!

For a limited time, I am making a fully functional version of Interaction available for free to anyone who participates in my quick online research study. This study, which requires about three minutes to complete, will help me greatly with my academic research.

To participate in the study, please click here. You will be able to download your fully functional copy of Interaction immediately after completing the study.

Thanks!  =)
