Statistics: Population vs Sample Means

If you are getting confused by terminology ("Mean of sample means ...") and the symbols in class I would highly recommend you take some time studying them (definitions in 5.3 and at the beginning of 5.1). It will definitely pay off in aiding your understanding. At this point, having put about a week into it, I am using them with the assumption that you are familiar and comfortable with them.



Homework is on the second slide. Essentially, we calculated some sample means and standard deviations from a known population mean and st. dev. and compared the two.

Statistics: Sampling Methods

Friday: We discussed the smapling methods on p.187 (poor sampling methods) and p.188 (good sampling methods). Homework was p.189 #1,2,3 No pictures for this day, sorry, but the notes in the book are quite good.

Monday: There was a substitute in on this day, and review questions were given for ch. 5.1 and 5.2
