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.

Thursday, April 2.

Hello class,
  This week's blog posting is an easy one. On class Tuesday, I handed out your SPSS assignment. I forgot to record who had which data set. So, for this week's posting, I would like you to write the 2 variables that you were given for the assignment. They are hand written on the top of the paper. Remember to post your name.
