Document Summary
The goal of ay scientist is to discover new information about the way the world works. May look at anecdotal evidence to support or refute hypothesis: anecdotal evidence: evidence gathered from others or self experience. Experiment: scientific tool used to measure the effect of one variable on another: eg/ energy drink enhancing marks. Independent variable: variable manipulated by the scientist: eg/ number of energy drinks consumed. Dependent variable: variable being observed by scientist: eg/ test scores. Experiment contains two groups of participants: experimental and control: experimental group receives manipulation of the independent variable during the experiment, control group does not receive manipulation of the independent variable during the experiment. Can compare the dependent variable measure for both groups. Eg/ test score experiment tests may get harder throughout the year: practice effect: improved performance over the course of an experiment due to becoming more experienced.
