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.
The best and most correct answer among the choices provided by your question is the first choice or letter A.

Answer:
Confirmation Bias
Explanation:
Confirmation bias is how one calls the tendency to interpret, favor, recall, and search for information in a way that it only confirms one's preexisting beliefs or hypotheses. Kayla is encountering a case of these propensities when she's evading data that would repudiate her convictions about the smartphone and gives uncommon consideration to the data that would bolster her decision. Also, it is important to add that the Selective Exposure theory expresses that individuals may have a propensity to favor data that strengthen their convictions while giving little consideration to data that would negate them.
Answer:
Forgetting curve
Explanation:
Ebbinghaus invented the forgetting curve by using different ways of savings at various time intervals. Ebbinghaus modern memory research began by using meaningless strings of letters to study the capacity of our memory system. The amount of previously saved letters decreases rapidly, but then reaches a plateau after which a decrease in percentage savings is minimal. We start by forgetting rapidly without practice and then at a certain point forgetting occurs a much lesser rate. With practice, the forgetting curve would look different.
