About the SETS development team members...

The SETS development team began as part of a CAUSEmos Stat Education Research cluster formed at USCOTS 2007. The team consisted of seven statistics educators/researchers located across the United States (listed alphabetically): Felicity Enders, Randy Groth, Leigh Harrell-Williams, Larry Lesser, TJ Murphy, Rebecca Pierce, and M. Alejandra Sorto. Information for the five remaining active members of the SETS team is listed below.
