TEST TOMORROW!

Below is an outline of tomorrow's test. At the very bottom of this post you can find the answers to both the multiple choice (from Tues) and open-ended classwork (from Weds) I gave you to practice.

Test Outline: Open Ended and 7 MC:

• Use the Normal model to find percents above/below/between (AP Question)
• Shaded model, z score, normalcdf(lower, upper)
• Use your "storms" problem to study--the questions are less direct, and make you think a little bit more, like (a) on the storms question
• Finding new summary statistics after shifting/rescaling...
• Just like our homework--the SAT/ACT problem or #1 on the open ended practice from today!
• Know which measures (spread or position) are affected by shifting/rescaling
• Use the Normal model to find "cutoff" values given a %
• Shaded Normal model, invnorm(% left, mean, Sx)
• Like 2fghi on the open ended from class today!
• Compare boxplots--draw conclusions, in context, based on comparison (not just comparing SOCS) (AP question)
• Determine if a distribution might be "approximately Normal" based on some summary values...(AP question)
• Create a boxplot, given data
• Remember: labels, title, and fence work!
• Calculate and interpret z-scores (in a sentence)
• MC "The caffeine content..."
• Use z-scores to compare values 
• MC #3
• Reading Ogives
• Find 5 number summary, IQR
• Categorical vs. Quantitative variables (which is which?)
• Know how mean/median relate for different shapes of distributions
• "Appropriate summary statistics"
