Data Distributions, Describing Variability and Comparing Groups (Connected Mathematics 2)

Students will learn to choose among a variety of representations to display distributions and will analyze, describe, and compare sets of data.
Exploring statistics as a process of data investigation involves a set of four interrelated components (Graham, 1987).
• Posing the question: formulating the key question(s) to explore and deciding what data to collect to address the question(s);
• Collecting the data: deciding how to collect the data as well as actually collecting it;
• Analyzing the data: organizing, representing, summarizing, and describing the data and looking for patterns in the data; and
• Interpreting the results: predicting, comparing, and identifying relationships and using the results from the analyses to make decisions about the original question(s).
This dynamic process often involves moving back and forth among the four components.
