Computer program: Microsoft Excel
 * Technology**

7th grade, Data Analysis and Probability: Read, create, and interpret box-and-whisker plots, stem-and-leaf plots, and other types of graphs when appropriate.
 * Curriculum Standard**

7th grade, Data Analysis and Probability: Analyze a set of data by using and comparing combinations of measures of center (mean, mode, median) and measures of spread (range, quartile, interquartile range), and describe how the inclusion or exclusion of outliers affects those measures.

Students will poll a group of students based on a question they would like to have answered such as "What is your favorite candy bar?" Students will be putting data into a spreadsheet using Microsoft Excel. They will create various types of graphs with this data and determine the mean, median, mode and range using different function equations of Excel. Here is a sample spreadsheet Candy Bars.xls

This article discusses the use of Microsoft Excel in the elementary and secondary school levels, especially with the gifted and talented students. It focuses on its use with data collection, creating graphs, and calculating relationships in mathematics curriculum.

This is tried and true (TT). Although it still uses technology, Mircosoft Excel has been around for years and is often used for this purpose. However, the way in which it is used in this activity is new for the students.
