Activity 1

Blowing Bubbles

Topic Area: Univariate Data

NCTM Standards:

• Formulate questions that can be addressed with data and collect, organize,

and display relevant data to answer them

• Understand the meaning of measurement data and categorical data, of

univariate and bivariate data, and of the term variable (9-12)

• Understand histograms, parallel box plots, and scatterplots and use

them to display data (9-12)

• Compute basic statistics and understand the distinction between a

statistic and a parameter (9-12)

• Select and use appropriate statistical methods to analyze data

• Find, use, and interpret measures of center and spread, including mean

and interquartile range (6-8)

• For univariate measurement data, be able to display the distribution,

describe its shape, and select and calculate summary statistics (9-12)

Objective

The student will be able to calculate univariate summary statistics, make

conjectures based on these statistics, and display the results in a box plot.

Introduction

You may want to use the following description or personalize it for yourself to

introduce the activity to the students.

"A friend of yours has not been too successful with blowing bubbles with her

bubble gum in the past. This sparks a question in your mind about how big most

people can blow bubbles. You realize that you could do an experiment and

calculate some simple statistics to help answer your questions."

You could also have the students create the experiment themselves. Setup the

classroom so that students can easily access a partner. You could have them find

their own partner, assign partners at the beginning of the activity, or use an

already established means of assigning partners.

The students should be familiar with the following vocabulary:

Univariate Interquartile range

Mean Conjecture

Box and whiskers Histogram

Median Mode
