STAT200 Introduction to Statistics Project 1

STAT200 Introduction to Statistics Project 1 worksheet

Objectives: To collect quantitative data, choose appropriate graphs for the data, and then interpret the data. Find the mean, median, mode, and standard deviation of your data.

Introduction: This is a very open ended assignment in which you will have to use critical thinking and the knowledge from week 2 to study a population using quantitative 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 appropriate graphs covered in chapter 2, 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 Data Sets for Projects”. You should collect/find data that is appropriate for a Histogram, pie chart, stem and leaf diagram, scatter plot, or time series. You should try several of the graphs. For example, for a histogram you could how many hours’ people exercised a week. For a time series you could look at a baseball player’s year by year batting average.

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. For a histogram think about if it 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_Project2 and turn it in through the assignments folder in LEO.
