Introduction to designing experiments
Description
Adam suspects that most hairy dogs have balding owners. Testing his "pet" theory at a local park, he quickly finds flaws in his own experiment. This video demonstrates Adam's second test, involving better preparation, more rigorous analysis, and an exciting pasta cook-off. Showing how Adam can effectively determine the best spaghetti recipe, the program illustrates concepts that are central to the scientific method-including null, alternative, and two-tailed hypotheses; field and lab settings; sampling; primacy/recency effects; constant/random errors; and other testing principles. Graphic screens reinforce each concept and enable students to fully absorb the testing process.
