The session will also address issues that can arise when analyzing longitudinal data, especially when the design of the data collection tools and process is out of your hands. The focus will be on how to address some common problems encountered and what can be done in the future to prevent them from occurring. Attendees will be invited to share their own experiences and suggestions for planning for longitudinal evaluation studies and analyzing the data.#2012Conference #HowTo #QuantitativeMethods-TheoryandDesign
