Imagine that we've asked 200 people to complete a 50-item survey. What are we going to do with these 10,000 responses (called data)? The next step in a research project involves data analysis, in which we summarize people's responses and determine whether the data support the hypothesis. In this section, we will review the three stages of data analysis: check the data, summarize the data, and confirm what the data reveal.

How do I check the data?

How do I summarize the data?

How do I know what the data reveal?
