Researchers can assume that studies
that use random sampling
always generate a representative sample that accurately
reflects
the population from which it was
selected................................................ True------
False
The vast majority of social work studies use probability sampling......... True------ False
Ans: (a) False because it is not necessary that studies that use random sampling always generate a representative sample. There are equal chances for a random sample tk be generated. However, in place of random sampling, stratified random sampling can be an important part of the process to create a representative sample
Ans: (b) True
Social work researchers usually try to select their cases using a random procedure in order to assure that no human bias exists in the selection process. They hope that the inferences they draw from their study will be maximally generalizable, statistically accurate, and useful. Using random procedures allows the use of probability sampling methods.
