Need a study converted to a different format?

You can contact User Support to inquire about the possibility of NAHDAP creating setup files for the study. If it is determined that we cannot create them or cannot create them within your time frame, then you are advised to seek assistance from someone on your campus with experience in the statistical package that you have chosen to use.

Alternately, we may be able to provide assistance in converting one of our studies into a statistical format other than the one in which it is offered. Generally, we offers data in SAS, Stata, and SPSS statistical packages but if one of those formats is not available for a specific study, we can convert any of these formats into any other. However, we do not typically provide data in analysis-ready formats when a setup file for the required format is offered. We offer tutorials on using setup files in all statistical packages on our YouTube Channel.

Video Presentations

NAHDAP has a number of video presentations on YouTube that address a variety of topics including step by step instructions on using and troubleshooting set-up files and creating a MyData account, or using data resources in your classroom.
