How Do You Measure Up?

Activity Overview

In this activity, students graph scatter plots to investigate possible relationships between two quantitative variables. They collect data and analyze several sets of data pairing the two quantities.

Before the Activity

See the attached PDF file for detailed instructions for this activity

Print pages 21 - 32 from the attached PDF file for your class

During the Activity

Distribute the pages to the class.

Follow the Activity procedures:

Measure the heights (cm) and the arm spans (cm) of class members

Enter the data as lists

Find the relationship between height and arm span

Graph the data as a scatter plot

Add the graph of line y = x on the scatter plot

Observe that the data points lie very close to the line y = x

Compute the ratio of arm span to height

Predict the arm span of a person of a given height, and guess the height of an individual with a given arm span

Repeat the activity with other quantitative variables

After the Activity

Students complete the Questions sheet.

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
