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 answer for that question is: increases ; increases
The positive behavior could increase the likelihood of the behavior by giving some sort of reward to someone if that person is doing a certain behavior.
The negative reinforcement could increase the likelihood of the behaviour by punishing that person if that person is NOT doing that certain behavior.
so in the end both reinforcements will increase the likelihood
Answer:
Reflecting feelings or reflection of feelings
Explanation:
When someone reflects on another person's underlying feeling in a statement to that same person that they are engaging in reflecting feelings or reflection of feelings. This is normally done by psychologist or by someone who is trying to educate someone in regards to their behavior. These underlying feelings are often reflected through behavior, way of talking and body language and therefore, can be an important tool for parents and teachers to evaluate children and assist them in understanding and regulating their feelings.
<span>Will is a scientist. He’s designing a spacecraft that would allow people to land on Mars. Will’s mass on Earth is 75 kilograms.
Will knows that the gravitational pull of Mars is less than the gravitational pull of Earth. When he lands on Mars, his mass will be greater to 75 kilograms. His weight on Mars will be lesser than his weight on Earth.
Hope this helps</span>
Answer:
B. seemingly minor differences in the wording of a question can convey vastly different meanings to survey respondents.
Explanation:
The fact that public support for government policies declines dramatically when calling the policies "welfare" rather than "assistance for the poor" illustrates that seemingly minor differences in the wording of a question can convey vastly different meanings to survey respondents.
Respondents may find the word welfare derogatory while assistance to the poor seems more acceptable. This could lead to a decline in the support of the public.
