Project URL:
http://www.teachnet-lab.org/unhs/mean.htm
Purpose of the project:
This unit combines mathematics and
technology to teach
students how to find the mean, median, and mode for a set of data.
How it works:
Using
the website http://forum.swarthmore.edu/,
students will define terms and find examples, as well as complete
practice exercises. They will then work cooperatively to analyze
real data from a variety of websites provided. To demonstrate
mastery and reinforce ELA performance objectives, they will explain the
procedure to a friend in an e-mail message.
Standards addressed:
Students will be
able to………
1. Organize, analyze and display
single-variable appropriately.
2. Solve verbal problems involving mean,
median and mode.
3. Utilize web resources to access
data for analysis.
4. Write an explanation of this study
and e-mail to a friend and to the teacher.
Computer Applications:
Internet access, e-mail
accounts
The Students:
The students were all 9th graders. Students met for about two days to
complete the project. They worked both in the classroom and in the
computer lab. The project can be adapted to any age. The higher the grade,
the more work can be done in terms of analysis and predictions.
Overall Value:
This a great project to introduce statistics.
The project can be started in the computer
lab and then continued in the classroom. Students love to see connections
with real life situations. This project will enhance their creativity and
will make them understand that math is the key to success.
Tips: You may substitute other web
sites with real data for the exercises, based on student interest and
ability level.
