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 people of Earth face many problems
Struggling just to live and maintain peace.
There's differences in language, faith and race
With misguided hated unwilling to cease.
To solve these problems that plague mankind
We must strive as never before.
Demanding justice with truth in settling disputes
While recalling the loss and heartbreak of war.
War is an emotional release for man
Practiced since the first stones were cast.
Could it be nature's way of thinning the numbers
As the fallen are consumed by the past.
Some have asked why must we study history
It just encourages us to live in the past.
When we forget God and submit to whatever
The sorrows of our sins forever last.
<span>The psychologist would perform a descriptive study. This would be done because these types of studies are much more illustrative than experiments or correlational studies in showing how a behavior is expressed by a person or group while in a specific time or place setting.</span>
Answer: secondary data
Explanation: Secondary data research is usually employed by social scientists in gauging economic and social progress. This they carry out by accessing available data such as stock market prices, unemployment rates, and statistics on health, welfare and so on. Secondary data research or analysis is one that was collected by another individual for a different primary purpose other than the one being carried out and thusly these existing data provides a viable option for researchers, scientists, analysts etc. who may have the required time and resources to carry out primary data analysis.
