Chapter 2: The Reasearch Enterprise in Psychology

Survey: Gathers lots of information quickly.

Social Desirability Bias: Answering how you want to be viewed rather than how you view yourself. EX. I view myself as an atheist but in a religious poll I would write I am a Hindu because everyone else also believes in religion.

Scientific Method Advantages- you know exactly what is causing the change, since all other variables are controlled-This sets a level field for everyone to accept the data, since you assign operational definitions

Experiment: research method where the investigator manipulates a variable under carefully controlled conditions-Advantages: you can create cause-effect relationships. -Disadvantage: you are limited to using theoretical environments to keep variables constant. Also, there are usually ethical problems with some experiments.

Natural Observation: a researcher observes subjects without interacting with them-Advantage: eliminates reactivity (change of behavior due to the presense of another person)-Disadvantage: difficult to turn data into numerical data

Case Study: an indepth study of one subject-Advantages: may lead you to find the roots of psychological disorders-Disadvantages: highly subjective, researchers focus obtaining info that fits their expectations, and the subjects don't represent general population

Statistics: the use of math to organize, summarize, and interpret data-Descriptive: organize and summarize data (central tendencies (mean, median and mode), variability (how much the values vary from one another and the mean), and correlation coefficient (a number between -1 to +1 that shows you the strength and relationship between 2 variables))-Inferential: interpret data and draw conclusions
