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.
Answer:
Increased attributes were ascribed by Egyptian figures to women and combining of animal characteristics with human like figures. Egyptian figures demonstrated deepness in human form and followed a practical human structure. For example, in Egyptian times, people of higher status would sometimes be drawn or sculpted larger than those of lower status. During the Dark Ages, people with more status had larger proportions than serfs. During the Renaissance images of the human body began to change, as proportion was used to depict the reality an artist interpreted.The scale used was the hieratic scale, portraying reality as god like figures. A typical example is Ti watching a Hippopotamus hunt.
Explanation:
Answer:
There will be 16 people who are both writer and editor
Explanation:
We have given there are total of 100 people
So total = 100
There are 45 writers so,Writers = 45;
It is given that there are more than 38 editors so ,Editors > 38
Both = x;
Neither = 2x
We know that
Total = Writers + Editors - Both + Neither
100 = 45 + Editors - x + 2x
x = 55 - Editors
We want to maximize x, thus we should minimize Editors minimum possible value of Editors is 39, thus:
x = Both = 55 - 39 = 16.
ADHD or the Attention deficit hyperactivity disorder is
treated by therapy, medication and a special diet or some combination of the
three or all of them combined. Usually the most common way to treat ADHD is with
the behavioral therapy coupled with social training, special school curriculum
and physical exercise. So, this is the treatment that would most likely be given.
The use of medication and a special diet can also be prescribed.
