Objectives
Students will be able to:
- Recognize the value of using data to make informed decisions
- Identify strategies for standardizing values of variables representing different units and different magnitudes
- Understand that different graphical representations can reveal different information about the context
- Identify strategies for using multiple variables in analyzing situations
About the Lesson
This activity is designed to involve students in considering a variety of data that can be used to make a decision. Analyzing the data can involve graphs, fractions, proportional reasoning, linear equations, and basic notions of probability. The fourth example of student work illustrates an application of z-scores for students who are familiar with statistics.
