Through our current grant (NSF DUE #1043814) we are able to pay a small stipend to undergraduate instructors who are willing to class test our materials. During the Spring 2013 semester we are testing two labs related to hypothesis testing:
Tangrams: One sample hypothesis tests
Tangrams: Two sample or paired hythesis tests This lab could also be used for 2-way ANOVA
Anyone can freely use the materials on this site. If you are interested in class testing these materials and receiving a stipend, please fill out the survey below:
Instructor Survey (prior to the activity): www.grinnell.edu/academic/mathstats/evaluation
After you submit your survey, you will be asked to use the materials within your course, fill out an instructor evaluation and ask your students to also fill out an on-line survey.
Instructor Evaluation (after to the activity): www.grinnell.edu/academic/mathstats/evaluation-2
Student Survey (after the activity): www.grinnell.edu/academic/mathstats/sef_tangrams
Please ensure that all students in your course use exactly the same spelling for their instructor name and institution.

Stat2labs was developed with partial support provided by the Transforming Undergraduate Education in Science (TUES).program at the National Science Foundation under DUE 0510392 and DUE #1043814
