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
New
York State Standards

- Students will use mathematical analysis, scientific inquiry, and engineering
design, as appropriate, to pose questions, seek answers, and develop
solutions.
- 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
environmental needs.
- 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
decisions.

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
data

The use of this type of graphic organizer to summarize large amounts
of data is shown on the site.
For each student:
- 1 small snack size package of Skittles or M&M candies
- One copy of each activity handout
For each lab pair:
- One computer terminal
- The use of a spreadsheet and graphing program such as Microsoft
Excel
