- 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.
