The unit Data About Us was created to help students:
- Understand and use the process of data investigation by posing questions, collecting and analyzing data distributions, and making interpretations to answer questions;
- Represent data distributions using line plots, bar graphs, stem-and-leaf plots, and coordinate graphs;
- Compute the mean, median, or mode and the range of the data;
- Distinguish between categorical data and numerical data and identify which graphs and statistics may be used to represent each kind of data;
- Make informed decisions about which graph or graphs and which of the measures of center (mean, median, or mode) and range may be used to describe a data distribution; and
- Develop strategies for comparing data distributions.
