Document Summary

It is better to have more than one observer so that more accurate results are obtained (inter-rater reliability or observer reliability) Expectations may influence your results as you may interpret things in a way that you shouldn"t. You can infer causation as long as the experiment is set up properly. Comes from the word to vary or to change. Two types of variables: independent variable (cause): variable. The variable that the experimenter manipulates or changes to see if it has an effect. The variable that is measured to see if the independent variable an effect: dependent variable (effect): The dependent variable is always dependent on the independent variable! The group that gets the 0 level (or the 0 amount) of the independent. The control experimental groups must be similar in every way except for the. Used as the basis for comparison. independent variable. Usually used in drug-related studies where people might have strong expectations about drug effects.
