4. A researcher gives a group of adults chocolate everyday at 3pm and measures their energy level and compares it to the energy level of another group who was not given chocolate.

Which of the following is the dependent variable

Adults

Chocolate

Energy level

Time in the afternoon

5. A researcher gives a group of adults chocolate everyday at 3pm and measures their energy level and compares it to the energy level of another group who was not given chocolate. Which of the following is the independent variable

Adults

Chocolate

Energy level

Time in the afternoon

6. The main purpose(s) of random assignment is

create groups as equal as possible before the manipulation of the IV

reduce the effects of nuisance/extraneous variables

distribute the timing of the treatment equally

A and B

7. “Dogs are smarter than cats” is an example of what type of research hypothesis

Nondirectional research hypothesis

Predictor research hypothesis

Nonpredictor research hypothesis

Directional research hypothesis

Solution

1.In this exercise we have four variables which are: Chocolate, adult, energy level and time in the afternoon. The above can be said that chocolate can not change because whether or not the person adult is going to eat, regardless of that will remain chocolate. If the adult eats chocolate may have a higher energy level compared to adults who do not eat, and the energy level necessarily depends on the chocolate according to the amount of chocolate that adults eat, the energy level can be raised or lowered this regardless of the hour.

so the energy level will be the dependent variable and the independent variable is chocolate

6.This question is the main goal is that focus groups are conducted in other words what is discovered in them is probably true.Therefore the experiments conducted under the same conditions and trigger events that can not predict in advance is a randomized. So the answer is the literal A

7. in my opinion this view may be non-directional hypothesis because these assumptions are not aimed at one result, but it is open to several possibilities that will give the answer after research done and tested. since we do not know that all dogs are smarter than cats may have exceptions. It can not be because no directional hypothesis focus their research in certain expected results.
