Data collection: We will use data from a large national survey that was de- signed explicitly with the goal of generating statistically valid infer- ences about the U.S. population.
Descriptive statistics: We will generate statistics that summarize the data concisely, and evaluate different ways to visualize data.
Exploratory data analysis: We will look for patterns, differences, and other features that address the questions we are interested in. At the same time we will check for inconsistencies and identify limitations.
Hypothesis testing: Where we see apparent effects, like a difference be- tween two groups, we will evaluate whether the effect is real, or whether it might have happened by chance.
Estimation: We will use data from a sample to estimate characteristics of the general population.
