Survey Says
  • Connections
    • NCTM Process Standard
    • Connections among the various areas of mathematics.
    • Connections between mathematics and the real world.
survey says1
Survey Says
  • Advice from the American Statistical Association
    • “… students should have the experience of applying their learning in settings as real as possible during their education. This could include co-ops, summer jobs, class projects …”

Ritter, Starbuck, and Hogg

survey says2
Survey Says
  • Introduction to Statistics is a service course at Shorter College and at Georgia Highlands.
    • A variety of majors: Business, Biology, Ecology, Middle Grades Education, Mathematics, Social Sciences, History
    • Concern that learning was disjointed and isolated from real life.
    • First conceived of a semester long project while working with Service Learning.
survey says3
Survey Says
  • Goals
    • Connect what was being learned in class with a real life application.
    • Connect the various elements of introductory statistics to each other.
    • Learn to use technological tools (calculators and computers) to organize and present data.
    • Give students an experience that would help prepare them for the use of statistics in their future careers.
survey says4
Survey Says
  • Volunteerism Survey: Collecting Data
    • Creation of a survey instrument
      • What types of data are needed?
      • How to word the instrument for clarity.
    • Types of sampling techniques
      • Random Sample
      • Systematic Sample
      • Stratified Sample
      • Cluster Sample
      • Convenience Sample
survey says5
Survey Says
  • Volunteerism Survey: Organizing Data
    • Database Entry
      • Standardize entry for consolidation
    • Frequency Distributions
      • Categorical
      • Ungrouped and Grouped
    • Graphs
      • Bar graphs
      • Pie Charts
survey says6
Survey Says
  • Volunteerism Survey: Analyzing Data
    • Measures of Central Tendency
    • Measures of Variation
    • Confidence Intervals
    • Single Population Hypothesis Testing
    • Two Population Hypothesis Testing
      • Did the sampling method appear to make a difference?
      • How do religious and non-religious volunteers compare?
survey says7
Survey Says
  • Volunteerism Survey: Presenting Data
    • Graphs and Charts
    • Written report
      • Connection with English
      • Connection with skills in Introduction to Computers
survey says8
Survey Says
  • Other projects
    • Television Sex and Violence Survey 1999
      • Data Collection Different
      • The need for training became apparent
      • Could be combined with literature research
    • Presidential Election Polls 2000 and 2004
      • Intersected with current political events
      • Very similar process to Volunteerism Survey
      • Students learned to use Minitab in 2000 and Excel in 2004
survey says9
Survey Says
  • Other Projects
    • Spring 2001
    • The groups proposed projects that I could approve or not approve.
    • I provided a list to help them “brainstorm.”
    • This made it easier for students to apply statistics to their field/particular interests.
    • There was unevenness in the amount of statistics used in the projects in terms of correlating to the topics covered in class.
survey says10
Survey Says
  • Other Projects
    • Statistical Analysis of SAFE 2002
      • An after-school program of the Rome City Schools
      • Combined Service Learning
      • Used this project to teach SPSS
      • By far the most important project
      • Disappointment with testing error that caused the data to be thrown out
survey says11
Survey Says
  • Other Projects
    • Statistical Analysis of the Tax Assessments for Residential Property in Floyd County 2003
      • Collection of data from the public records at the Tax Assessor’s Office

survey says12
Survey Says
  • Other projects

      • Testing the claims from Internet sites on the Golden Ratio
      • Data Collection and Entry into Excel
      • Descriptive Statistics
      • Confidence Intervals and Hypotheses Testing
      • Correlation and Linear Regression
survey says13

    • Both individual and group work
survey says18
Survey Says
  • Result of One Student Survey
    • 94% agreed with “These projects helped me to better understand statistical concepts.”
    • 82% agreed with “Using the same data set repeatedly has helped me to see there is a range of statistical procedures (techniques) that may be used to investigate/answer the same question.”
    • 97% agreed with “These projects helped me to learn how to construct graphs and tables for statistical analysis.”
    • 82% agreed with “Working in groups helped me to learn to communicate statistical ideas.”
