Document Summary
Research process is sometimes more important than answers. Goal to improve on hypothesis constantly being developed. Emphasis on methods by which knowledge can be obtained: more concerned with better understand human nature than with specific facts. Technical training teaches one to use what is already known. Scientific training teaches one to explore the unknown. Research exploration of the unknown: essential aspect is the gathering of data. Reliable data measurements that reflect what you are trying to assess and are not affected by anything else. Measurement error (error variance) the cumulative effect of such extraneous influences: state, trait. 4 things can undermine reliability: low precision measurements should be taken as exactly as possible, as carefully as possible. 4 ways to improve reliability: be careful double check all measurements, proofread, make sure procedures are understood by assistants, use a constant, scripted procedure for all participants.
