- How tests are chosen and standardized to study individual differences
- How data are recorded, presented, and checked for accuracy
- How researchers interpret results while guarding against bias
- How conclusions are supported by complete, accessible data sets
Ideal for readers interested in the history of psychology, research methods, and the science behind testing intelligence and abilities.
