Researchers gain knowledge about a seemingly haphazard situation by collecting information about a variable. This information is called data. This sub-module explores the two methods for classifying data. The type of data determines what statistical analysis can be performed on the data.
Once the researcher has collected the data, he or she must organize the data in some meaningful way, in order to describe situations, draw conclusions, or make inferences. In this lesson, we focus on how to present qualitative data using tables and graphs.
