DRAWING INFERENCES ABOUT POPULATION MEANS AND PROPORTIONS

  • Identify the types of variables you would need to conduct:
    • a Chi-square (for students whose last name begins with A-H)
    • one-sample t-test (for students whose last name begins with I-P)
    • paired t-test (for students whose last name begins with Q-Z)
  • Be sure to explain the number of dependent and independent variables, and the types of dependent variables necessary for the statistical analysis.
  • Provide a health-related example (or use a peer-reviewed article that used the statistical analysis) to explain your answer.
