Collecting Data and Graphing
An AskERIC Lesson Plan
AUTHOR: Gala Rountree, Dickson Junior High School, Dickson, TN
SUBJECT AREA: Mathematics
To collect, organize, and arrange information in a pictograph
To create a survey and administer it to the class
To find the range, mode, median, and mean of a set of data
To create a pie, bar, and line graph on a computer
GRADE LEVEL: 8
Multiple computers; printer
Software: word processing, compatible graphing
Overhead projector with teacher-prepared transparencies
Packages of M&M candies (both plain and peanut)
TIME REQUIRED: 4 class periods
ACTIVITIES AND PROCEDURES:
Have the students work in groups to count the different colors of M&M's
in each kind of package and then draw a pictograph to show the results.
Have each group write a program to show their results and then compare the
manually-drawn and computer graphs.
Discuss with the class the differences in and results of the two methods.
Brainstorm with the class to identify data to graph (favorite pizza, sports,
musical groups, pets).
Have the student groups use the word processing software to create a survey.
Have them print copies and administer it to the class, then tabulate results
on a chart.
Teach "Range," "Mode," "Median," and "Mean" concepts. Have each group put
their survey results on the board for others to copy. Have the students find
the range, mode, median, and mean for each survey.
Have the groups create a database with the data and display the data as a
pie, bar, and line graph.
