What is a prediction of the outcome of a research study
100
Does not need to be fully planned in advance and deviations in the plans can not only be tolerated but might be welcomed as well. Semi-structured interviews might be used in gathering qualitative data.
What is qualitative research
100
All members of a population must be identified and each member of the population must be given an equal chance of being selected.
What is random sampling for quantitative research
100
The group in which the researcher is ultimately interested.
What is a population
100
This is the opposite of maximum variation sampling, individuals who are similar in important ways are purposively selected.
What is homogeneous sampling
200
They are usually stated near the end of a literature review because the review establishes the context and rationale for them.
What is a hypotheses
200
This can be used to explore causality, but is typically used for this purpose only when it is not possible to conduct an experiment by administering treatments to participants.
What is nonexperimental research
200
When individuals are handpicked to be participant because they have certain characteristics that are believed to make them especially good sources of information.
What is the purposive sampling for qualitative research
200
Allows researchers to estimate how likely it is that the results have been influenced by random sampling errors created by the random sampling.
What is inferential statistics
200
This is synonymous with purposive sampling but reserved for use when very clear cut, specific criteria are established for identifying potential participants.
What is criterion sampling
300
should refer to observable behaviors and be sufficiently specific to guide the planning and conduct of the research.
The same percentage of individuals is drawn from each subgroup at random.
What is stratified random sampling
300
This consists of giving each member of a population an equal and independent chance of being selected.
What is simple random sampling
300
This is sometimes called chain sampling or network sampling, the initial participants identify additional participants for a study
What is snowball sampling
400
A hypothesis must have at least two variables,
What are an independent variable (treatment variable) and a dependent variable (outcome variable).
400
The results are reduced to numbers, typically scores or frequency counts that can be analyzed with statistical methods.
What is quantitative research
400
This type of sampling (also known as accidental sampling) for quantitative and qualitative research: using individuals who happen to be convenient as participants in research.
What is convenience sampling
400
This is an initial study that is conducted to determine feasibility.
What is a pilot study
400
This is when purposive sample is too large, individual scan be selected at random using random selection.
What is random purposive sampling
500
This should be stated in a way that the answer cannot just be "yes" or "no".
What is the way a research question is written
500
This might be the reason to: explore a cause–and-effect relationship.
What is the purpose of experimental research
500
A sample that is representative of it population in terms of key variables is drawn.
What is stratified sampling for quantitative research
500
In any procedure for drawing a sample that gives some types of individuals a greater chance of being included in the sample that other types.
What is biased sampling
500
When cases are selected so that the full range of characteristics of interest are present in the sample.
