Check out this key for the matching we did in groups last Friday!
- The test will take the full period (I think). You have all 46 minutes.
- The test has some free response (numbers 1-8 but they all have multiple parts) and 4 AP multiple choice
- Here's what you should know:
- Identify if a variable is categorical or quantitative
- Calculate probabilities with a two way table (like all of our Titanic stuff or the quiz we took about eye color/sex)
- Be sure you can also determine independence based on two answers (look at the Titanic stuff)
- Describe a distribution given a boxplot or histogram
- Know how to read/analyze boxplots/histograms
- Estimate median, range, mode, and sample size from a histogram
- Produce the 5 number summary, IQR, and range from a boxplot
- Know how to determine if there are outliers in a data set and use this info to sketch a boxplot
- Compare boxplots (like our hours of sleep for days of the week, or other homework questions where we look at boxplots to determine highest/lowest median, range, IQR, etc.)
- Determine the shape of a distribution given the 5 number summary/determine the shape of a boxplot
- Know how mean and median relate based on the shape of a distribution (skewed left, skewed right, symmetric)
- Know how adding an "extreme value" would/would not affect mean, median, mode, range, midrange, IQR, standard deviation (know what is 'sensistive to extremes' or not)
- Read ogives--use an ogive to estimate range, IQR, produce the 5 number summary
- Find a combined/overall mean given two different samples and their averages
