Document Summary

The scientific approach to behaviour: goals of the scientific enterprise, measurement and description, develop measurement techniques that make it possible to describe behaviour clearly and precisely, understanding and prediction, make and test predictions (hypothesis) Hypothesis tentative statement about the relationship between. Variables any measureable conditions, events, characteristics, or behaviours that are controlled/observed in a study: application and control, scientists hope that info gathered will be of help to solve everyday problems (practical) Research methods consist of various approaches to the observation, measurement, manipulation, and control of variables in empirical studies. Experiment research method in which the investigator manipulates a variable under carefully controlled conditions and observes whether any changes occur in a second variable as a result. Allow researchers to detect cause-and-effect relationships: independent and dependent variables. Purpose of experiment: find out whether changes in 1 variable (x; independent) cause changes in another variable (y; dependent)
