Q

What is confidence limits

A

The upper and lower bounds around an estimate of a population parameter based on a sample statistic. The confidence linked shows how much confidence can be placed in the estimate

Q

What is multistage cluster sampling

A

Sampling in which elements are selected in two or more stages, with the first stage being the random selection of naturally occurring clusters and the last stage being. The random selection of multilevel elements within clusters

Q

What is purposive sampling?

Q

What is quota sampling

A

A nonprobability sampling method in which elements are selected to ensure that the sample represents certain characteristics in proportion to their prevalence in the population

17
Q

What is random digit Dialing

A

The random dialling by a machine of numbers within designated phone prefixes, which creates a random sample for phone surveys

18
Q

What is random number table

A

A table containing lists of numbers that are ordered solely on the basis of chance; it is used for drawing a random sample.

19
Q

What is random sampling error

A

Differences in population and the sample that are due to chance

20
Q

What is simple random sampling

A

A method of sampling in which every sample element is selected only on the basis of chance, through a random process

21
Q

What is stratified random sampling

A

A method of sampling in which sample elements are selected serparately from population strata that are identified in advance by the researcher

22
Q

What is systematic bias

A

Overrepresentation or underrepresentation of some population characteristics in a sample resulting from the method used to select the sample; a sample shaped by systematic sampling error is a biased sample.

23
Q

What is systematic random sampling

A

A method of sampling in which sample elements are selected from a list or from sequential files, with every nth element being selected after the first element is selected randomly within the first interval
