The end result of sampling is to get a representative sample, or a small collection of units or cases from a much larger collection or population. In theory, the researcher can study the smaller group and produce accurate generalizations about the larger group. Researchers focus on the specific techniques that will yield highly representative samples much so in similarities as a population. Quantitative researchers tend to use a type of sampling based on theories of probability from mathematics, called probability sampling.Sampling is the group of individuals who participate in your study. These are the individuals who will participate in a qualitative study. People who could have been participants in your study but did not actually participate are not considered part of your sample.
Answer:
Step-by-step explanation:
The common ratio is given as 2, so the base of any exponential must be 2 (not -2 or 2.25). The 4th term is negative, so the initial value must be negative (since the multiplying factor is positive). The only selection matching these requirements is d.
You know the general term is ...
... an = a1·r^(n-1)
so the 4th term is
... -18 = a1·2^(4-1) = 8·a1
Then the first term is ...
... a1 = -18/8 = -2.25 . . . . . confirms our choice of answer d.
