What is Sampling
selecting events from a population
100
Has characteristics that reflect the population from which it is drawn
What is Representative sample
100
Samples are defined based on the known proportions with the population
What is Quota Sampling
100
method by which researchers select respondents according to a predetermined schedule rather than a random sequence

100
What is the ideal size for having a sample size
large sample size
200
Numbers computed from population
What is Parameters
200
Sample Size
What is Must decide on the amount of sampling error the researchers are willing to accept
200
Selection of events that are mostly readily available
What is Accidental of Convenience Sampling
200
method by which researchers select participants or events such that each event in the population has an equal chance of being selected
What is Simple Random Sampling

300
The universe of events from which the sample is drawn
What is population
300
Difference between sample and population characteristics ; the degree to which a sample differs from the population on some measure
What is Sampling Error
300
Selection of events based on referrals from initial information
What is Snowball Sampling
300
A method by which researchers selects participants or events to represent known proportions in the population
What is Stratified Random Sampling
300
a measure that attempts to summarize the average deviation of scores from the mean, by estimating such a value from the square root of the variance s^2, symbolized for the sample standard deviation as s.
What is the definition of standard deviation
400
Numbers computed from a sample
What is Data
400
Selection of data such that each event in the population has an equal chance of being selected
What is Random Sampling
400
1.)Strength: "non random sampling methods often allow the researcher to get samples that would otherwise be unavailable." 2.)Weakness: " non random samples tend to show great bias"
What is a strength and weakness of nonrandom sampling (look in book)
400
Techniques, and the use of randomization plays an important part in research to identify samples
What is Probability Sampling

500
In sampling the tendency for the sample to err so that it fails to represent the population
What is bias
500
Confidence Intervals
What is indicate a range of values or “margins of error” of sample statistics within which a relevant population parameter is likely to fall
500
Selection of events from groups that are known to possess a particular characteristics under investigation
What is Purposive or known group sampling
500
Two or more stages, is used when researchers cannot get a complete list of the members of the population they wish to study. However, they can get a complete list of a group or cluster they wish to study
What is Cluster Sampling
