Answer to Question 1

Implicit deception involves keeping participants unaware of the actual reason for the task they are engaging in. Technical deception relates to misrepresentation as to how equipment is being used. Role deception pertains to false statements about the role of other presumed participants in a study.
According to research by Fisher and Fyrberg, most participants (about 90 percent) felt that implicit deception was not a problem. More participants were bothered by technical and role deception, but the majority (70 percent) still thought that deception was not troublesome.

Answer to Question 2

The Student's t-test has traditionally been used for comparing two groups. It is not appropriate for multiple groups or multiple variables because the probability of a Type I error (rejecting the null hypothesis when you shouldn't) increases with each t-test you do; if you do multiple tests, you are more likely to reject the null when you shouldn't.
