TCAP COACH LESSON 4 Drawing Conclusions and Identifying Bias and Errors

Getting the Idea • A good experiment is designed so the experimenter can reach a valid conclusion. • A valid conclusion is one the experimenter and other people can trust. • A conclusion can be trusted if no errors occurred during the experiment. • Errors may include misinterpreting the cause of an effect.

Bias • Bias can also lead to errors in an experiment. • Bias is a wish, conscious or unconscious, to have an experiment lead to a certain conclusion.

Drawing Conclusions • An experiment is conducted to test a hypothesis. • A conclusion states whether the results of an experiment support the hypothesis. • The conclusion should take the independent and dependent variables into account.

Publishing Conclusions • It is important to describe procedures accurately. • This allows for other scientists to repeat exactly. • This is called conducting trials, if all later trials support the same results, then the hypothesis is proven.

Experimental Error • Mistakes and false results • Experimental Error is a mistake in an experiment that can lead to false results.

Guarding Against Bias • Double Blind Testing • Review experiments • Any other suggestions? ?
