Data About Us
Concept with Explanation
Selected Homework from ACE
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, stemandleaf 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.
