Activity Overview
Students compare their height with the average height of students in the classroom. They create histograms to analyze the data, and construct boxplots to summarize the height statistics.
Before the Activity
Use TI Connect™ to download Vernier EasyData™ application
Connect the calculator to the CBR 2™
See the attached PDF file for detailed instructions for this activity
Print pages 23 - 34 from the attached PDF file for the classroom
Set up the calculator for data collection
During the Activity
Distribute the pages to the students.
Follow the Activity procedures:
Set up a long wooden board at a certain height such that the student can just stand beneath it
Position the CBR under the board such that it can take readings without any obstructions
Using the calculator and the CBR, measure the heights of 12 students and the teacher
Graph all the data points and view their coordinates
Observe that the plots are Distance versus Events
Understand that Events stand for independent variable and Distance stands for dependent variable
Sort the data in the distance list in ascending order
Create a box-and-whisker plot
Line the data on the number line on the worksheet, and identify the median and the quartiles
Use the calculator to verify the answers
Analyze the boxplots and the whiskers
Present the data in a histogram
Answer the questions listed on the student worksheet
After the Activity
Students analyze the results of the case analysis questions on the student worksheet
Review student results
As a group, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
