Test Tomorrow! #morestudying

Tomorrow we have our in class multiple choice test! Study! It covers anything we've learned thus far (in Unit 1), from chapters 2, 3, 4, 5, and 6. Use your take home test to study--make sure you do some research and figure out anything you had incorrect on the take home test!

Here is a breakdown of the topics covered on our 20 multiple choice questions...

• Matching histograms/boxplots (like our quiz!)-
• Find the mean given 2 groups (like #8 on take home test)
• Finding "x" in the z-score formula (using algebra like when finding SD from z-score formula)
• Find a cutoff given a percentile (invnorm problems!)
• Calculate and interpret z-scores
• How does changing numbers in a data set effect summary statistics? (we had 2 MC where outliers were removed or moved as a warmup--like these!)
• Analyze and interpret graphical displays (stemplots and boxplots)
• Compare boxplots
• Histograms--reading them, finding median (like #2 on take home test)
• Shifting and Rescaling (like #4 on take home, or like #1 on "Ch. 6 Quiz A")
• Finding a percentile (make sure you understand what a percentile is!)
• How does shape affect the mean/median? (#10b on take home test)
• Comparing z-scores (like Boxers/Dalmations on "Ch. 6 Quiz A")
• Calculating %'s from a contingency table (a more wordy version of #5 on take home test)
• Comparing SD's--which has the highest/lowest SD? (think about the matching we did with data sets to histograms--how did you know which had the highest SD? Lowest?)
• Interpret Q1/Q2/Q3 (Think--what's Q2 the same as?)
• Describe shape of a distribution
