                         Getting a Grip on Graphing – A Data and Statistics Project

 In this project you will be using prices and a survey to analyze data and create two specific graphs about
 different brands of the same product (include pictures). Each brand should be the same size.

 Part A PRICE LIST – Give prices for 8 or more brands. Find the Range, Mean, Median, and Mode.
                     PA/pg 39 – 40; Alg 1/pg 875 - 876

 Part B BOX and WHISKERS PLOT (all prices) - Find the Five Number Summary and create the Box Plot.
                   PA/pg 588 – 590; Alg 1/pg 887 - 889

 Part C CIRCLE GRAPH (four or more brands) - Survey your product (20 – 30 people) and create a
                  PA/pg 595; Alg 1/pg 935                                            Circle Graph.

 Part D ANALYSIS QUESTIONS
        1) Why do you think different brands of the same product have different prices? Explain
        2) The Box Plot contains numerical data and the Circle Graph contains categorical data. Explain
