Here's an outline of what's on your test tomorrow!
- The test has both free response (FR) and multiple choice (MC) questions
- Use your chapter quizzes, our first mid-unit test, and your take home test to study!
- Find percentages above/below/between with the Normal curve using normalcdf (study the "classifying storms" problem we did in class!) (ch. 6)
- Find data values that cut off a given percentile/% above/% between using invnorm! (ch. 6)
- Compare boxplots IN CONTEXT! (study the last question from our chapter 5 take home quiz, along with the rubric I provided yesterday!) (ch. 5)
- Describe the shape, center, and spread of a given histogram/dotplot/stemplot (ch. 4)
- Know how the mean and median compare for different shapes of distributions (symmetric, skewed left, skewed right) (ch. 4)
- Read a stemplot to find median, range, percentiles (% below) (ch. 4)
- Know how shifting/rescaling affects measures of position and spread, and calculate these new values (study the table about Yuans on your take home test!) (ch. 6)
- Identify which dotplot/histogram/stemplot has the highest/lowest standard deviation (study our matching histograms to 6 variables classwork!) (ch. 5)
- Know how to calculate a z score and interpret its meaning in a complete sentence (ch. 6)
- Find probabilities from a two-way table (study the SSRI question on our first test, or look at the Titanic problems in chapter 3!)
- Reading boxplots--now the meanings of Q1, Median, Q3 as percentiles (what % of data falls below/above/between these values) (ch. 5)
- Completely identify the shape of histograms (ch. 4)
- Create graphical displays--boxplots, dotplots, stemplots, dotplots (ch. 4/5)
Use the multiple choice practice from today's class to study! The answers (and questions) are below--this is a bunch of practice for you!
