1. Sample
the set of elements selected form a population
2. Element
The basic unit selected
3. Population
The full set of elements from which the sample is selected
4. Sampling
The process of drawing a sample from a population
5. Representative sample
A sample that resembles the population
6. Equal propability of selection method (EPSEM)
Sampling method in which each individual element has an equal probability of selection into the sample
7. Statistic
A numerical characteristic of sample data
8. parameter
A numerical characteristic of a population
9. sampling error
differences between sample values and the true population parameter
10. Census
collection of data form everyone in the population
11. Sampling frame
A list of all the elements in a population
12. response rate
the percentage of people selected to be in a sample and who participate in the research study
13. \Biased sample
a nonrepresentative sample
14. Proximal similarity
generalization to people, places, settings, and contexts that are similar to those described in the research study
15. Simple random sampling
A popular and basic equal probability selection method
16. Statified random sampling
Division of population elements into mutually exclusive groups and then selection of a random sample from each group
17. Proportional stratified sampling
Stratified sampling where the sample proportions are made to be the same as the population proportions on the stratification variable
18. disproportional stratifies samples
Stratified sampling where the sample proportions are made to be differnet from the population proportion s on the stratifcation variable
19. Cluster random sampling
Sampling method where clusters are randomly selected
20. Cluster
A collection type of unit that includes multiple elements
21. One-stage cluster sampling
Clusters are randomly selected and all the elements in the selected clusters constitute the sample
22. Two-stage cluster sampling
Clusters are randomly selected, and a random sample of elements is drawn from each of the selected clusters
23. Systematic sampling
The samplking method where one determines the sampling interval(k), randomly selects an element between 1 and k, and then selects every kth element
24. Sampling interval
the population size divided by the desired sample size; it's symbolized by the letter k
25. periodicity
Problematic situation in systematic sampling that can occur if there is a cyclical pattern in the sampling
26. Convenience sampling
use of people who are reeadily available, volunteer, or are easily recruited for inclusion in a sample
27. Quota Sampling
A researcher decides on the desired sample sizes or quotas for groups identified for inclusion in the sample, followed by convenience sampling fron the groups
28. purposive sampling
a researcher specifies the characteristics of the population of interest and then locates individuals who have those characteristics
29. Snowball sampling
each sampling person is asked to identify other potential particpants with the inclusion characteristic
30. Random selection
Selection of participants using a random sampling methods
31. Random assignment
Placement of participants into experimental conditions on the basis of a chance process
32. purpose of random selection
to obtain a representative sample
33. Purpose of random assignment
to produce two or more equivalent groups for use in an experiment
34. Sample size calculator
A statistical program used to provide a recommended sample size
35. mixed sampling
use of a combination of quantitative and qualitative sampling methods
