Document Summary
A: certain variable make people behave certain way. A way of proving causation: change only one variable at a time. Eg. how people behave due to alcohol. Alcohol experiment(effect of alcohol on balance): one day with alcohol and one day without alcohol- perform same task of walking on beam. Everything else has to be constant control variables except for alcohol has to be same. Iv: how you are measuring, something the experimenter changes in the experiment. Dv: what behaviour- the measure of behaviour. Measurements: using time (seconds/time) and distance (feet/meters) Independent variable- x: comprehension (reading for interest and reading for understanding and summarize) Dependent variable-y: reading speed (words per minute) (behaviour) Z: room temperature, no talking, same computer screen. As subjects go through the tests they get better. Control progressive error by counter-balancing: making an average. Counterbalancing (making sure each condition benefits from practice equally) is used to control the practice effect. Random error is fixed by calculating averages.
