1. Avoiding Bias a. Identifying information, you can tell a study lacks bias if it has been peer reviewed, has a wide range of evidence, and the testing was done with controlled and variable tests, and if applicable with a wide range of subjects. b. Identifying biases: i. Measurement - systematic error in measurement of key ingredients ii. Selection - when the participants of a study do not fully represent the population iii. Confirmation - favoring information that supports their beliefs, and ignoring or downplaying what does not c. Peer review is important just in case for them to maybe catch bias you didn’t, and to make your hypothesis more reliable and perhaps turn it into a theory 2. Classifying Organisms a.
