STAT 200 Introduction to Statistics Project

Objectives: To collect qualitative data, choose appropriate graphs for the data, and then interpret the data.

Introduction: This is a very open ended assignment in which you will have to use critical thinking and the knowledge from week 1 to study a population using qualitative variables. It will be important to understand what you population is and what your sample is. Your sample must be appropriate for your population. You will organize your data into a frequency distribution and create several graphs, then describe what the graphs tell you about the data.

Procedure: Start off by asking yourself what you would like to learn about a population. See the work sheet below. You can either collect your own data, use one of the data sets provided in LEO, or find an appropriate data set on the internet. There are data sets available in LEO under “Content à Data Sets for Projects”. You should collect/find data that is appropriate for a bar/pie chart and for either a comparative bar chart or multiple bar chart. For example, for a bar/pie chart you could collect data on car makes in the BX parking lot like in the example in the book. For a comparative bar chart you could ask some people how many hours they spend on various activities. Each person would be a category and the hours for each activity the variable.

Once you have your data, organize the data in an excel spread sheet, then make the appropriate graphs. Be sure to label the axes and add a chart title. Think about if your chart should use the frequency or relative frequency. Once you are happy with your charts, copy and paste them into your assignment worksheet and answer the questions. Also copy and paste your data onto the work sheet.

Save the document as Lastname_Project1 and turn it in through the assignments folder in LEO.
