Document Summary
Bogus pipeline technique- a procedure in which research participants are falsely led to believe that their responses will be verified by an infallible lie detector. Interrater reliability- the degree to which different observers agree on their observations. Random sampling- selecting a group of people randomly so that the population is represented properly. Correlational research- research designed to measure the association between variables that are not manipulated by the researcher; examines the relationship between two or more variables. Correlation coefficient- a statistical measure of the strength and direction of the association between two variables. Represented by the letter r and ranges from -1 to 1. Positive is where variables move in the same direction. Negative is where the variables move in opp directions. The bigger the number is (closer to -1 or 1, stronger the relationship is) Means that correlation does not mean there is a cause and effect relationship.
