Questions and Answers

- 1.________ is the process of selecting observations.
- 2._______ is the quality of a sample having the same distribution of characteristics as the population from which it was selected.
- 3.________ is the quality of a research finding that justifies the inference that is represents something more than the specific observations on which it was based.
- 4.______ is the unit about which information is collected and that provides the basis for analysis.
- 5.A ________ ________is the list or quasi-list of units that compose a population from which a sample is selected.
- 6.______ is the theoretically specified aggregation of study elements.
- 7._________ __________is the sampling method that typically involved some random-selection mechanism based on probability theory.
- 8._________ ___________ is a probability sampling procedure in which each element has an equal chance of selection independent of any other event in the selection process.
- 9.A ________ is the summary description of a given variable in a population.
- 10.________ _________, even if never perfectly representative, are typically more representative than other types of samples because of the avoidance of sampling biases.
- 11.________ _________ ___________ is a type of probability sample in which units that compose a population are assigned numbers.
- 12._________ ___________ is a type of probability sample in which every
*k*th unit in a list is selected for inclusion in the sample. - 13.________ _________ is the standard distance between elements selected in the sample.
- 14.__________ ___________is a probability sampling procedure that uses stratification to ensure that appropriate numbers of elements are drawn from homogeneous subsets of that population.
- 15._________ ______________ ____________is a sampling method aimed at ensuring that enough cases of certain minority groups are selected to allow for subgroup comparisons within each of these minority groups.
- 16._________ is a procedure employed in connection with sampling whereby units selected with unequal probabilities are assigned weights in such a manner to make the sample representative of the population from which it was selected.
- 17.__________ _____________is a multi-stage sampling procedure in which natural groups (clusters) are sampled initially, with the members of each selected group being subsampled afterward.
- 18.________ _________is also referred to as convenience sampling.
- 19.________ _________is a type of sampling in which units are selected into the sample on the basis of prespecified characteristics so that the total sample will have the same distribution of characteristics as are assumed to exist in the population being studied.
- 20.In practice, there is greater likelihood that a _________ sample will be representative of the population from which it is drawn than will a _________ sample.
