Statistics Project     2 Davenport University November 25 th , 2008 Statistics Project The sample set that I chose to analyze for my project is a set that was provided  by my instructor. The sample set was originally collected from  Consumer Reports  it  focuses on nationality of the manufacturer, horsepower of each car, and displacement  of the car in cubic inches from the list of 38 cars.  Through my analysis of my sample  set I used many different types of graphs and tables that were taught throughout the  semester, including: frequency distribution table, descriptive statistics, histograms, box  plots, dots plots, ogives, frequency distribution plots, scatter plots, and a few others. In order to begin the analysis of my sample set, first it is necessary to form  frequency distribution tables for each column of data.   For my frequency distribution  tables of horsepower and displacement I decided to have 5 classes of data.  To find the  class widths, you must take the highest piece of data and subtract the lowest, and  divide that number by how many classes you decided to have.  For example, for the  horsepower column, the highest piece of data is 155, and the lowest is 65, so you take  155-65 which equals 90, and then you take and divide 90 by how many classes you
