Levels of measurement: categorical", ordinal, quantitative* *Note: In this course, levels of measurement will be classified according to terms used in the Gerstman textbook. Nominal is a synonym for categorical. Continuous, scale, interval, and ra are synonyms for quantitative. Student Name: Scenario 1: Researchers tested whether a new drug called AMP50 (DRUG) could shrink cancer cells. Two hundred patients were recruited from a large university hospital; half were given the new d while the other half were given a placebo. The results indicated a statistically significant reduction in tumor volume (TUM) for patients taking the new drug as opposed to patients taking the placebo. Coding for study variables: DRUG- 1 = AMP50 drug; 2 = placebo TUM- tumor volume (V = (L x W*)/2); 0-300 cm Question ANSWER 1. What study design was used in this scenario? 2. What was the independent variable? 3. What was the dependent variable? 4. What is the level of measurement for DRUG? 5. What is the level of measurement for TUM
