If a particular sample has 36 participants and the other sample has 40 participants the total degrees of freedom for the study is?
v = n1 + n2 - k n1 = 36, n2= 40 and k=2 v = 36 + 40 - 2 v = 74
Difference between sample and sampling frame?
A sample is a smaller group selected from a larger population. It may be to costly and time consuming to carry out the study on the whole population so the researchers choose a sample and often generalise results.A sample frame is the list of people from which a sample for the study are selected. It is only carried out on the target population that the researcher is interested in studying. For example finding data on just school children would not involve the the whole population only children in schools.
What is he conclusion from research conducted on a sample population to the population as a whole?
Assuming that the population was carefully defined, the sample population was carefully and correctly chosen, and that there were significant results, then the implication is that the results of the study, within the confidence limits indicated, hold true for the population at large.
What is volunteer sampling?
This is another way of saying self selected sample. This sampling technique consists of participants becoming part of a study because they volunteer when asked or in response to an advert. This technique, like opportunity sampling, is useful as it is quick and relatively easy to do. It can also reach a wide variety of participants. However, the type of participants who volunteer may not be representative of the target population for a number of reasons. For example, they may be more obedient, more motivated to take part in studies and so on. Suppose, for example, that a news show asks viewers to participate in an on-line poll. This would be a voluntary sample. The sample is chosen by the viewers, not by the survey administrator.
Sampling is a method of estimating population?
Sampling makes it possible to make assumptions about the larger population based on a small sample. This is beneficial in the study of population and demographics.
What is a sample study?
sample is the population we make our study about them.
What is the sample of milgram's study?
The sample of Milgram's study on obedience to authority consisted of 40 male participants recruited through newspaper advertisements. They ranged in age from 20 to 50 years old and represented a diverse range of occupations and educational backgrounds. The participants were compensated for their time and participation in the study.
Is the subset of the population chosen by the investigator for a study?
The subset of the population chosen by the investigator for a study is known as the sample. Sampling involves selecting a smaller group of individuals from a larger population to make inferences or generalizations about the broader population. The goal is for the sample to be representative of the population so that findings from the study can be applied more broadly.
If a particular sample has 36 participants and the other sample has 40 participants the total degrees of freedom for the study is?
v = n1 + n2 - k n1 = 36, n2= 40 and k=2 v = 36 + 40 - 2 v = 74

How do sampling methods effect the rigor of a study?
A sample needs to be random and if not a simple random sample of the whole population then a stratified random sample (there are different ways to stratify). Otherwise the study is a waste of time.

What is the potential bias of the longitudinal Dunedin Multidisciplinary Health and Development Study conducted in 1972 and ndash1973 lies with?
One potential bias of the Dunedin Multidisciplinary Health and Development Study is selection bias, as participants were chosen from a specific population. Another potential bias could be attrition bias, as participants may drop out of the study over time, affecting the representativeness of the sample. Additionally, there may be response bias in self-reported data, where participants may not provide accurate information.

What effect does non-random sample have on what you can say about the results of a study?
It means that the results of the study cannot be claimed to hold for the entire population from which the sample was drawn. The researchers can only claim that their results hold for the individuals selected into their sample.
