Part I (approximately 1–1½ pages, total):

Copy and paste the following examples (1-6 below), then respond by classifying each of the following variables as either: nominal, ordinal, interval, or ratio. Provide a brief explanation where indicated.

  1. A researcher studying lifespan      categorizes individuals into single, married, divorced, or widowed. What      type of variable measurement is this?
  2. A cognitive scientist places      her subjects into categories based on how anxious they tell her that they      are feeling: “not anxious,” “mildly anxious,” “moderately anxious,” and      “severely anxious,” and she uses the numbers 0, 1, 2 and 3 to label      categories where lower numbers indicate less anxiety. What type of      variable measurement is this? Are the categories mutually exclusive?
  3. A Physician diagnoses the      presence or absence of disease (i.e., yes or no). What type of variable      measurement is this?
  4. A person weighing 200 lbs. is      considered to be twice as heavy as a person weighing 100 lbs. In this      case, what type of measurement is body weight?
  5. A nurse takes measurements of      body temperature on patients and reports them in units of degrees      Farenheit as part of a study. What type of variable measurement is this?
  6. Patients rate their experience      in the emergency room on a five point scale from poor to excellent (1 =      very poor, 2 = not very good, 3 = neither good nor bad, 4 = quite good,      and 5 = excellent). What type of variable measurement is this? Is the      difference between a 1 and a 2 necessarily the same as the difference      between a 3 and a 4? Explain briefly.

Part II: Statistics (1/2 page)

Given what you’ve learned in this module about the meaning of “statistics,” choose one of the examples from Part I (1-6), and raise a relevant question of your own that could be answered by a statistician. Then without answering your own question, explain how a pattern could be studied or a useful prediction made based on data that are to be collected.

Part III: Quantitative vs. Qualitative Data (approximately 1–1½ pages)

A health scientist wishes to measure how well participants diagnosed with Post Traumatic Stress Disorder are coping. Explain how a variable such as coping could be measured quantitatively or qualitatively.
