Objective(s)
Students will collect data from Internet and graph using a
box-whisker graph and stem-leaf plot.
National Standards
Technology: use technology to locate, evaluate, and collect
information from a variety of sources.
Mathematics: (5) interpret data using methods of exploratory
data analysis.
Summary
In this lesson, students will use the Internet to search for
data--30 or more values. With that data, students will interpret
and graph using a box-whisker graph and a stem-leaf plot.
Technology and/or Materials Needed
- Computers with Internet access
- Calculators (optional)
- List of websites or website directory
- Prerequisite: searching skills, knowledge of graphing
Implementation Time Frame
Three-four 45-minute class period
Activities
This lesson should follow a unit on statistics where students
have been taught different types of graphs including the box
whisker graph and stem leaf plot. This may be used as a culminating
assignment or additional assignment.
Students will use the Internet to gather at least thirty pieces
of data. A list of possible websites may be provided as well
as a website directory. Also, examples of possible data can be
shared, such as the number of NBA rebounds by the top thirty
players, weather temperatures around the globe, or the MVPs'
number of homeruns for the past thirty years. Students should
be encouraged to search for data that interests them. You should
circulate while the students are collecting to the data to discuss
with them whether the numbers are feasible and/or realistic to
work with for this project.
Once they have collected the data, they can print out the
list or write down the data set. The next step is to create a
box whisker graph(s) and a stem leaf plot(s). They should also
include the calculations of mean, mode, median, and range. Finally,
each student needs to complete a written summary and conclusion
of this data, describing how they found the data and what the
graphs are displaying.
Assessment
Students may be assessed for accuracy using point values:
Data collection=5 points
Box whisker graph=15 points
Stem leaf plot=15 points
Conclusion=15 points
Total=50 points
