Experimental Design. Student Cheat Sheet 2017. Variables. Independent variable (IV): the variable that is purposely changed in an experiment. Dependent variable (DV): the variable that responds to the change (IV). It is measured or observed. IV groups.
Experimental Design. Hw 3. RECap : scientific method. The Water Cycle. Earthquakes & Tsunamis. Earth’s Seasons. Science. We’ve learned a lot of bad ways (fallacies) for figuring out whether claims are true. There is a good way of finding things out: science!
Experimental Design. A researcher can most convincingly identify cause-and-effect relationships by using an experimental design In such a design, the researcher considers many possible factors that might cause or influence a particular condition or phenomenon

Introduction. Good experimental design allows you to:Isolate effects of each input variableDetermine effects due to interactions of input variablesDetermine magnitude of experimental errorObtain maximum info with minimum effort. The fundamental principle of science, the definition almost, is thi
