Power Series

Today we had the second in our series of three power analysis presentations. Jason Cole (UCLA alum and outside consultant) talked in depth about effect size, the proper alpha level and multiplicity issues to an audience of 42. Within the next week, we hope to post the audio portion of Jason's presentation along with a pdf of his powerpoint slides.

Last week, for Christine's presentation, we had almost sixty people in attendance. This created problems because the Visualization Portal is not meant to hold that many people. For this week's presentation we had to have people register on-line to limit the number attending.

We are looking forward to another big crowd for our third power analysis presentation in two weeks.
