What is a carefully worded statement of the exact procedures and how variables will be measured used in a research study?
Which correlation coefficient demonstrates the strongest correlation?
-0.92
+0.11
+0.67
If researchers want to test to see if the results of a study is reliable, they should:
ensure that conditions are assigned randomly
replicate the experiment using the same procedures
organize the hypothesis appropriately
focus on the descriptive statistics that are measured
identify all of the variables in the study: independent, dependent and confounding
Research particpants are randomly assigned to one of three groups. One group listens to a list of words, another group reads a list of words, and the third group hears and reads the words. The researcher then tests the participants' memories to see how many words the members of each group can recall. The way the words are presented is which type of variable?
Confounding
Dependent
Independent

All of the following are American Psychological Association (APA) ethical guidelines for researchers EXCEPT:
Research may not involve deception
Participiation must be voluntary
Participants must be informed of potential risks
Participants must be offered alternative activities if research participation is a course requirement
Particpants' right to privacy must be protected
This modern approach to psychology focuses on how the brain and body enable sensation and emotions.
