Question

Identify phenomena/variables that lend themselves to self-reports, observation, and biophysiologic measurement and discuss each of these types of data collection

Answer 1

Ans) Phenomena that researcher are interested in must be translated into data that can be analyzed. Most of the time researchers seek to find their own data instead of relying on past data. To do this they need to decide what type of data to gather.

(PRO) are participants responses to questions. Most common type.
-Observation: people's behavior
-Biophysiologic measures- used to assess important clinical variables.
-Strive for objective results
-Methods tend to be quantifiable and structured, with the same information gathered from all participants in a comparable, prespecified way.
