Document Summary
Experimental research: one out of several ways of testing your phenomenon, which involves: beginning with a hypothesis, modifying something in the situation, and comparing the outcomes to the modification: we tend to use variables. Dependant variable: the variable we seek to understand (i. e. amount of tips a server receives) Independent variable: the force we manipulate (i. e. interaction with customers) Control variable: a constant variable or set of variables you control (i. e. male/female servers, ambiance in room, food pricing). The idea is that you can compare it with the changes you made (independent variable). This type of research design allows: the researcher to observe causation. It can demonstrate causation, that allows researchers to actually observe causation instead of it being implied: causation hinders on 3 conditions: Temporal order: change in iv must occur before the dv. Association: as values in the iv increase, the dv.
