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, 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.
