PSYC 202 Lecture Notes - Lecture 13: Level Of Measurement, Participant Observation
Document Summary
Examples (a. 1. b. 1) gender: male & females (a. 1. b. 2) eye color: brown, blue, green, black (a. 1. b. 2. a) we would represent this by assigning numbers to them as placeholders. Allow us to rank order the levels of the variable being studied but do not involve quantitative distinctions. 1st, 2nd, 3rd (a. 2. b. 2. a) we know there is a difference between them and the order, but don t know the exact value that differentiates them: continuous quantitative. The difference between the numbers on the scale is meaningful. Zero on any interval scale is only an arbitrary reference point (b. 1. c. 1) zero does not indicate the absence of the variable being measured. Zero scales do have an absolute zero point. Reactivity: when behavior changes as a result of the observation process. Allow the participant to get accustomed to being observed. A. 2: what type of research would this affect. Quantitative: numerical terms: frequency, duration, average, percentages, rating scales, Qualitative: non-numerical terms, verbal labels: example: swipe left or swipe right.
