Research Methods part.2
- Hindsight bias- tendency of people to overestimate their ability to have predicted an outcome that could not possibly have been predicted.
- Single-blind-a test or experiment in which information that may bias the results is concealed from either tester or subject.
- Double-blind-test or trial,in which any information that may influence the behavior of the tester or the subject is withheld until after the test.
- Mean-average
- Median-The average of the two middle numbers,
- Mode-value that appears most often in a set of data.
- positive correlation- relationship between two variables in which both variables move in the same direction

i feel that a double blind study would be a nice experiment to conduce because of how both the sample and experimenter have no clue of the experiment going on!!
ReplyDeleteI agree with Franklin. In a single- blind study, the participant doesn't know but the experimenter knows. The mere knowledge alone might trigger hindsight bias from the experimenter which might cause the experimenter to experience an unprecedented confounding variable.
ReplyDeleteIf the double blind study means that the participant doesn't know its being tested wouldn't that throw off your results due to your predication maybe result in being completely wrong?
ReplyDeleteI like how you shorten the definitions of each term,but I think it'd best if you organize a little bit better and have the same text font.
ReplyDeleteI don't really think the double-blind study would throw you off your investigation, it could actually help eliminate any bias the researcher or the subject have. It would be the most natural way to administer an experiment.
