AT HOME COMPUTER ACTIVITY

Instructions:

1)    Go to collegeboard.com – enter this URL:

http://apcentral.collegeboard.com/apc/members/courses/teachers_corner/21972.html

2)    Click on “Interpreting Graphical Displays of Distributions of Univariate Data” (the first one) – you should see this page below:

3)     Explore the three selected links below:

Interpreting Graphical Displays of Distributions of Univariate Data
 
 
 
 
  Dotplot, Stemplot, Histogram, Cumulative Frequency Plot

Rossman/Chance Applet Collection
Histograms are very useful, but care needs to be taken in constructing and interpreting them. The Histogram Bin Width java applet from the Rossman/Chance Applet Collection allows the user to vary the bin-width of the histogram.

R. Webster West’s Java Applet
This applet uses a data set from the Old Faithful geyser in Yellowstone Park. The application allows the user to vary the bin-width of the histogram to show students how the number of bins affects the shape. For larger bin widths, the bimodal nature of the Old Faithful data is no longer apparent.

Gallery of Data Visualization
The Best and Worst of Statistical Graphs by Michael Friendly provides examples of good and bad statistical graphs in order to allow the user to examine the contrast between the two.

4)     From the page you started on, back up a page and then select “Summarizing Distributions of Univariate Data.”  Explore the applets you see listed below:

Home > AP Courses and Exams > Course Home Pages > Summarizing Distributions of Univariate Data

 

 

Summarizing Distributions of Univariate Data

 
 
 
 
  Mean and Median Applet
This java applet from the Rice Virtual Lab in Statistics shows the relationship between the mean and the median for a set of data, beginning with the construction of a histogram. The user can add values to the dataset to examine the resulting effect on the mean and median.

Surfin’ Sinefeld
Two flash animated statistics activities for exploring the measures of center and the measures of spread are available on this site. The investigations allow the user to choose from six DASL datasets and make changes to the datasets to see the resulting effect on the summary statistics.

5)     Go back and explore “Comparing Distributions of Univariate Data – there is also a link under MORE.

Comparing Distributions of Univariate Data
 
 
 
 
  Dotplots, Back-to-Back Stemplots, Parallel Boxplots

Exploring Data
This Web site offers a wealth of information for both the new and experienced statistics teacher. The site has numerous worksheets to explore boxplots (including instructions for constructing parallel boxplots), and several worksheets for working with and constructing stemplots (including the “Greed Game” link that has students construct back-to-back stemplots after playing the second round of the game).
   Boxplots
   Stemplots

Comparing Distributions
A java applet from the Rice Virtual Lab in Statistics records your response times to a simple motor task under two conditions. Various statistics, histograms, and boxplots are presented to allow for a comparison between the distributions.

Explore some more on your own at home (either these suggested or other ones not on this sheet but on the actual website).  Let me know if you find some other site/activity particularly helpful.
