What is in Unit 2?

In Unit 2 we learn to explore, analyze and summarize data. We use the ideas from Unit 2 throughout the course.

Unit 2 contains four modules. Each module contains explanations and examples, numerous low stakes quizzes to help you assess your understanding and learn from your mistakes, a discussion item or two that may require data analysis using technology, and a Module Checkpoint quiz. At the end of Unit 2, there is a Unit 2 Checkpoint quiz that covers all four modules.

How is Unit 2 related to the Big Picture of Statistics?

In Unit 2 we focus primarily on the second step in a statistical investigation: exploring, analyzing and summarizing data.

As a reminder, here are the steps in a statistical investigation:

1. State a research question

2. Produce Data: Determine what to measure, then collect the data.

3. Explore the Data: Analyze and summarize the data (also called exploratory data analysis or descriptive statistics). (Unit 2 is part of the step.)

4. Draw a Conclusion: Use the data, probability, and statistical inference to draw a conclusion about the population.
