Document Summary

In experimental designs, there are two kinds of variables: independent variable (iv, dependent variable (dv) The variable that is systematically manipulated is the independent variable. This also can be called the treatment variable. The outcome variable that is measured after the manipulation has been carried out is called the dependant variable. The dependant variable is measured after the independent variable has been manipulated. A good way to remember dependant variables: focus on the d it depends on data the dependant variable depends on the experimental manipulation. (provides the experimental data) In experiments, the independent variable is manipulated by the experimenter. Independent variables are causal variables and dependant variable are effect variables. A researcher conducts an experiment that tests the hypothesis that anxiety has an negative effect on a student"s exam performance. In the experiment, the experimenter will focus on examining the impact that manipulations of anxiety can have on student"s exam performance.
