Next Class (April 14) we will have individual meetings. I want you to bring your SPSS project and I will give you advice on how to improve any stakes. Each of you will be alloted a five minute time frame. For this week's posting, I would like you to select you time. This way you don't have to sit around all class. Lets start with 5:30 and go in 5 minute intervals until 6:30 (i.e. 5:30, 5:35, 5:40, etc.). Please post your name and select a time not chosen by another student.
