Question | Answer |
The larger group to which research results are generalized refers to what? | Population |
The reference group for estimating characteristics of or drawing conclusions about the population is know as the? | Sample |
This happens when individuals in a sample overrepresent or underrepresent certain population attributes that are related to the phenomenon under study. | Sample Bias |
The universe of interest is known as the what? | Target population |
The portion of the target population that has a chance of being selected is know as the? | Accessible population |
This describes the primary traits of the target or accessible populations that will qualify someone as a subject | Inclusion criteria |
Factors that would preclude someone from being a subject are known as? | Exclusion criteria |
To use this sampling technique, the researcher divides the total number of elements in the accessible population by the number of elements to be chosen. | Systematic Sampling |
What type of sampling involves identifying relevant population characteristics, and partitioning members of a population into homogeneous, nonoverlaping subsets based on these characteristics? | Stratified random sampling |
What type of sampling involves successive random sampling of a series of units in the population? | Cluster Sampling |
This occurs when sample are chosen on some basis other than random selection. | Nonprobability sampling |
What is the most common form of nonprobability sampling? | convenience sampling |
What form of nonprobability sampling involves choosing subjects on the basis of availability? | Convenience sampling |
This is a form of nonprobability sampling in which stratification is used to obtain representative proportions of specific subgroups. | Quota Sampling |
This form of sampling involves the researcher hand picking subjects on the basis of specific criteria. | Purposive sampling |
This form of sampling is carried out in stages, initially subjects who meet selection criteria are identified and tested, the subjects are then asked to identify others with the requisite criteria. | Snowball sampling |
The ability to find significant differences when they exist is know as? | Power |
With a small sample does power tend to be high or low? | Low |
