Mike would like to find out if a new intervention would increase the motivation to study chemistry in high school students. He recruits 40 high schoolers and gives the intervention to 20 of the students. He then measures attitudes towards studying chemistry in all the students and compares the results for the students who got the intervention with the students who did not. Mike's study... A. Has a non-directional hypothesis and should be tested with a dependent samples t- test B. Has a non-directional hypothesis and should be tested with an independent samples t-test C. Has a directional hypothesis and should be tested with an independent samples t-test D. Has a directional hypothesis and should be tested with an dependent samples t-test
Lecture(8.4): Researchers were interested in whether the number of books children carried differed between gender. It was hypothesized that girls would carry more books than boys.Twenty children were recruited and matched based on age and SES..Researchers then collected the number of the age of the appropiate books the children carried.
