5 – Q6. For each of the following research questions, you will read an independent and dependent samples study to test that research question. Identify which study used independent and which used dependent samples. Q5. Researchers hypothesized that the more wins a team has, the more teammates will believe in their own abilities (self-efficacy). To test this, they selected a group of sports athletes from teams with few wins during the previous season and a second group of sports athletes from teams with many wins during the previous season. They tested whether self-efficacy significantly differed between groups. Q6. Researchers hypothesized that dopamine would increase in response to a high-fat food (reward) versus a similar low-fat food. To test this, they presented four adult female Macaca fascicularis monkeys with a high- and low-fat raisin and measured the levels of dopamine in the brain in response to each reward. They tested whether the difference in dopamine levels was significantly different.
