AP Statistics

## Upcoming Assessments

Graded Quick Check on Histograms Friday, 9/6

## Chapter 1 - Exploring Data

Topics in Chapter 1 - Exploring Data

• Classify variables as categorical or quantitative.
• Display categorical data with a bar graph. Decide if it would be appropriate to make a pie chart.
• Identify what makes some graphs of categorical data deceptive.
• Calculate and display the marginal distribution of a categorical variable from a two-way table.
• Calculate and display the conditional distribution of a categorical variable for a particular value of the other categorical variable in a two-way table.
• Describe the association between two categorical variables by comparing appropriate conditional distributions.
• Make and interpret dotplots and stemplots of quantitative data.
• Describe the overall pattern (shape, center, and spread) of a distribution and identify any major departures from the pattern (outliers).
• Identify the shape of a distribution from a graph as roughly symmetric or skewed.
• Make and interpret histograms of quantitative data.
• Compare distributions of quantitative data using dotplots, stemplots, or histograms.
• Calculate measures of center (mean, median).
• Calculate and interpret measures of spread (range, IQR, standard deviation).
• Choose the most appropriate measure of center and spread in a given setting.
• Identify outliers using the 1.5 x IQR rule.
• Make and interpret boxplots of quantitative data.
• Use appropriate graphs and numerical summaries to compare distributions of quantitative variables.

**All bold concepts have already been covered in class.

**You are expected to be able to answer ALL problems in the textbook (not just those assigned).  Use the unassigned problems as practice for the test.

Study Recommendations:

• Reread the textbook Ch1 (if it's in the textbook, you are responsible for it)
• Make a reference sheet for Ch1 (one sheet of paper with all facts covered in Ch1)
• Do lots of practice problems (do ALL of the problems and examples in Ch1... see Ms. Tecce for correct answers to evens)
• Watch videos and try exercises on Khan Academy that are relevant to our topics
