This purpose of this section is to help librarians learn how to design quantitative research projects, analyze their data and present this data in a meaningful way. These sites can help with both the basics and more sophisticated designs.
We welcome suggestions for additional web sites. For this section, please send suggestions to John S. Spencer (spencer@gonzaga.edu) or Janelle Hedstrom (jhedstrom@austin.utexas.edu).
