Here is a breakdown of the topics on the test: The test has both open ended (free response) and multiple choice questions.
- Create a histogram (using your graphing calculator, like last night's homework)
- Create a boxplot by hand (given a table of summary statistics, like our summer academy notes or last night's homework)
- Know how to find outliers given a data set (this is part of the boxplot process, but could also be it's own question--calculate the fences!)
- Identify variables as categorical or quantitative (provide units for quantitative variables!)
- Use your calculator to find the "1 Var Stats" (mean, standard deviation (Sx), median, min, max, Q1, Q3)
- Calculate probabilities from a two-way table (like our Titanic homework)
- Determine if two variables are related (or independent; remember, independent = not related; this was also on our Titanic hw)
- Identify the explanatory variable (IV) and response variable (DV) given the context of a study
- Determine if a study was a survey, experiment, or observational study
- Reading histograms (like last night's "heights" problem)
- Find sample size
- Estimate the maximum possible range
- Find the proportion (%) of data values above/below a given value
- BONUS: estimate the median (what two values it falls between)
- Reading boxplots
- Identify the median, Q1, Q3, and outliers given a boxplot
- Calculate the IQR (Q3 - Q1) given a boxplot
- Calculate the range (Max - Min) given a boxplot
- Find the overall mean given two samples (we took notes on this in day 3 of the summer academy)
- Know which graphical displays are appropriate for categorical or quantitative data
Most of this test reviews the content from the summer assignment and what we've learned over the past week...
- Look over your homework and the answer keys provided
- Look over your class notes
- Look over your summer assignment...
- These questions from your summer assignment will be reflected on your test:
- #6
- #7
- #13 to 17
- #19 to 22
- #23
- #26, 27
