ANOTHER LOOK AT DATA (HISTOGRAMS AND BAR GRAPHS)


ESTIMATED TIME TO COMPLETE: 75 minutes

MODULE OBJECTIVES: Students will construct and distinguish among the appropriate uses of bar graphs and histograms through activities with Interactive software

CONCEPT(S) LEARNED IN THIS MODULE: Appropriate uses of bar graphs and histograms

STANDARDS ADDRESSED BY UNIT MODULES:

TECHNOLOGY - ENHANCED INSTRUCTIONAL STRATEGIES UTILIZED IN THIS MODULE:

Computer based estimation, analysis and visualization

Component

Brief Description of Module Activities

Student Grouping

Materials/Technology

Engagement

Have students use unifix cubes to construct a 3-D bar graph display of surface area of oceans of the world.

Small Group

Unifix Cubes, data sheets

Exploration

Use Histogram tool in Interactivate at www.shodor.org site to distinguish the differences between bar graphs and histograms

Individual or Small Group

Computer with web access, computer projection device

Explanation

Teacher directed activity on changing scales on histogram to affect visual interpretation

Whole class

Computer with web access, computer projection device

Extension

Students will independently explore the other data sets in Histogram tool to gain insight into visual manipulation of data.

Individual

Computer with web access

Evaluation

Students would find sets of environmentally related data and construct a bar graph & two histograms (different intervals)

Individual

Computer with web access

EXPECTED MODULE OUTCOMES:

Students will be able to:

PERFORMANCE BASED ASSESSMENT OF MODULE OUTCOMES:

Students will construct three displays - one bar graph and two histograms (different intervals) - and complete a compare and contrast chart of the information shown. A three-circle Venn Diagram is recommended for chart.
