Answer:
The correct answer is D.
Explanation:
A confounding variable is a variable that you didn’t account for. It is when an experimenter cannot tell the difference between the effects of different factors on a variable. This method is used to influence the outcome of experimental design.
Answer: The process by which Dr. Blakely is putting together a set of integrated factors to explain Stephen's disturbance is: Clinical Picture.
Explanation: A clinical picture is all of the details and particulars that relates to a patient state. As the name says, a clinical picture is a picture or an integration of multiple factors that are causing and mantaining disturbances to the patient.
<u>In this case, Dr. Blakely is constructing a clinical picture, but since he is a behavioral psychologist, his clinical picture is certainly influenced by the behavioral theory. </u>

<u>In conclusion, Dr. Blakely is putting together a clinical picture because he is integrating all of the details and factors that are causing disturbances to the patient.</u>
It should be noted that the main goal when normalizing is to decompose relations, therefore, the statement given is true.
It should be noted that the main goal during normalization include the minimization of data redundancy and simplifying the enforcement of referential integrity.
Also, normalization makes it easier to maintain data and decompose relations with anomalies to produce smaller, well-structured relations.

Hello. This question is incomplete. The full question is:
"Dr. Parrett is a sports psychologist for a large Southern university. The provost and chancellor have asked him to examine the relationship between athletic performance and academic stress at the university. For example, is it the case that the most talented athletes experience the greatest concern over their grades? The provost and chancellor have made it clear to Dr. Parrett that they want a large amount of external validity in the study. He has valid and reliable measures of both athletic performance and academic stress. He knows that he does not have the time or the money to study the entire population of interest.
Imagine that Dr. Parrett wants to use a nonrepresentative sampling technique. Name the three types of nonprobability sampling and explain how each one could be used by Dr. Parrett."
Answer:
The four types of nonprobability sampling are convenience sampling, purposive sampling, quota sampling, and snowball sampling.
Explanation:
Convenience sampling: Allows a selection to be made of a small sample of the target population of the research. This sample is made up of individuals who are available and accessible to research and not through statistical criteria. Regarding the question above, Dr. Parrett can select the athletes he knows and who would like to participate in the research.
Purposive sampling: It allows the sample to be controlled whenever a certain manipulation is possible to generate expected and known results. In the case of the question above, Dr Parrett can search for specific athletes, with characteristics that will generate an expected result in the research.
Snowball sampling: Allows the individuals who make up the sample to invite other individuals to compose the sample, who in turn can invite other individuals. In the case of the question above, Dr. Parret can invite the athletes he wants and ask them to call friends to participate in the survey as well.
Sampling quota: Allows the individuals who will compose the sample to be selected due to their characteristics and qualities. Regarding the question above, Dr. Parrett could only summon athletes with high marks.
