In this world of ever-increasing information our students must learn
to collect, analyze, and interpret data for practical application and
problem solving. This lesson unit is designed to streamline the introduction
of several graphical organizers and how to use them most effectively.
The students will visit Internet sites to learn of new data presentation
modes and how to interpret various types of data.
Students will be able to:
- Demonstrate good random sampling techniques for data collection
- Select and develop graphic presentations of data
- Analyze the data to solve a problem presented
York State Standards
- Students will use mathematical analysis, scientific inquiry, and engineering
design, as appropriate, to pose questions, seek answers, and develop
- Students will access, generate, process, and transfer information
using appropriate technologies.
- Students will apply technological knowledge and skills to design and
construct, use, and evaluate products and systems to satisfy human and
- Students will understand the relationships and common themes that
connect mathematics, science, and technology and apply the themes to
these and other areas of learning.
- Students will apply the knowledge and thinking skills of mathematics,
science, and technology to address real-life problems and make informed
Council of Teachers of Mathematics Standards
Students will be able to:
- Understand patterns, relations, and functions
- Formulate questions that can be addressed with data and collect, organize,
and display relevant data to answer them
- Select and use appropriate statistical methods to analyze data
- Develop and evaluate inferences and predictions that are based on

Median, and Mode
This page deals with making sense of data in statistical terms. The
concepts of mean, median, and mode are introduced to the students.
This page is used to teach setup and use of frequency tables for statistical
The use of bar graphs is illustrated on this page. Students are exposed
to a number of different versions of histograms.
and Leaf Plots
Stem and leaf plot development and use are introduced on this Web page.
Line graphs and their use in data interpolation and/or extrapolation
are found on this page.
Pie charts or circle graphs are shown to illustrate the organization
of data by percent of the whole.
and Whisker Plots
The use of this type of graphic organizer to summarize large amounts
of data is shown on the site.
For each student:
For each lab pair:
- 1 small snack size package of Skittles or M&M candies
- One copy of each activity handout
- One computer terminal
- The use of a spreadsheet and graphing program such as Microsoft
- One floppy diskette
