Rather than a topic for discussion, Lets use this posting to sign up for a meeting, next Monday, July 24. If you remember from class, rather than formally meeting in class, we will meet individually throughout the day to discuss your final paper. Please, post a time you would like to meet (between noon and 8 pm) and make sure you give 20min between meetings. Email me with any questions. See you Monday.

July 10 & 12

Good work this week class. First, your SPSS assignments have been graded and are posted on Vista. Many of you did very well but some missed the mark a bit, but I'm going to give you an opportunity to make back some of the points you lost. For review, this week we covered,
1.) ANOVA (Analysis of Variance)
-Main Effect
-Interaction Effect
- Post-hoc test
2.) Modes of Administration for surveys
3.) Non-probability vs. Probability sample
4.) Deficiencies in sample frame
5.) Different types of Sampling
6.) contributors to response rate
7.) Types of Survey designs
8.) Constructing Questions for surveys
9.) Margin of error

Question for thought,
Usually, when taking a survey, the instrument asks for demographic data (age, gender, income, etc.), even when this information has no bearing (say, my horror film viewing habits and aggressive nature is the study). Why then, do you think demographic information is still asked?

Monday, July 3

No Class today! "Enjoy your country's Independence day by blowing part of it up." Be safe class and try to find some time to study before the midterm on Wednesday. Email me if you have any questions.
