Document Summary
Psychology textbook chapter 2: methods in pscyhology. Notes written by zara hoffman. Empiricism: how to know stuff. The scientific method is a procedure for finding truth by using empirical evidence. The art of looking: need empirical method (a set of rules and techniques for observation) to gather accurate information. Observation: discovering what people do. Observer bias: expectations can influence observations and reality. Use double- blind (an observation whose true purpose is hidden from both the observer and subject) observation to avoid this. 1 away from x, 95% of the data is within 2 s of x, and 97. 7% is within. Just the essential numbers and calculations from data, used when you need to summarize. Includes mean, median, mode, range, and standard deviation. Explanation: discovering why people do what. Manipulation: critical to experimentation and is a way around the third- variable problem.
