6Risk of errors in sampling can be set very low by using nonprobability sampling methods and by reducing the sample size.

7Sampling errors occurs from chance, the random error that is introduced into any sample that's taken from a population.
- AVerdadero
- BFalso
8Random error can be avoided by reducing sample size.
- AVerdadero
- BFalso
9We cannot reduce sample bias by increasing sample size.
- AVerdadero
- BFalso
10Controlling sample bias is achieved by careful attention to the sampling process, defining a population of interest, careful selection of representative sample from population, and having success in obtaining responses from the sample group.
- AVerdadero
- BFalso
11Non-sampling errors can occur in all of these, except.
- AThe data gathering process
- Bmisunderstanding a response
- Cbeing tired and missing response

- Eall of these can occur
12The definition of a [blank_start]population[blank_end] consists of four parts: element, sampling unit, extent, and time.
- Apopulation
13For general population surveys, a traditional sample frame has been the [blank_start]telephone directory[blank_end]. In the U.S., 95 percent of potential respondents can be reached by [blank_start]telephone[blank_end].
- Atelephone directory
- Btelephone
14With nonprobability sampling a random or a systematic, chance-based procedure is utilized to select the study elements,
- AVerdadero
- BFalso
15Probability sampling procedures tend to be more objective and allow the use of statistical techniques.
- AVerdadero
- BFalso
16From a operational perspective, probability sampling offers the advantage of being less expensive and quicker to implement.
- AVerdadero
- BFalso
17A common analogy for this sampling method is the traditional drawing of a sample from a fishbowl containing slips of paper with names of elements of the sampling frame.
- Astratified sample
- Bcluster sample
- Csystematic sample
- Dsimple random sample
18Systematic sampling is often associated with area sampling.
- AVerdadero
- BFalso
19Convenience sampling is a probability sampling method.
- AVerdadero
- BFalso
20Man on the street is an example of this type of sampling.
- AConvenience
- BQuota
- CJudgement
21Focus group recruitment is an example of a judgement sampling process.
- AVerdadero
- BFalso
22A particular kind of judgement sample is the [blank_start]snowball[blank_end] sample, which relies on the researcher's ability to locate an initial group of respondents with the desired characteristics.
- Asnowball
23The difference between quota sampling and stratified sampling is that quota samples do not use random sampling from the categories, as we do in stratified sampling.
- AVerdadero
- BFalso
24The 90% confidence level is suggested for most research.
- AVerdadero
- BFalso
25Probability sampling techniques include the convenience sample, judgment sample, and quota sample.
- AVerdadero
- BFalso
26Companies that do repeated studies over time to gather similar information to compare data and determine trends tend to use ___________ to determine the sample size for the current study.
- Aprevious sample sizes
- Bquota samples
- Cmagic number
- Dask an expert
- Euse typical sample sizes
27Quota sampling is a nonprobability sampling technique, while a stratified sampling is a probability technique.
- AVerdadero
- BFalso
28Out of all possible samples of a certain determined size of coin flips, 95 percent from the actual population by no more than three percentage points indicates a margin of error of 3 percent.
- AVerdadero
- BFalso
29Random error cannot be avoided, but can be greatly reduced by decreasing the size of the sample.
- AVerdadero
- BFalso
30A random sampling method is a example of a non-statistical method of determining sample size.
- AVerdadero
- BFalso
31Check the reasons why the sampling technique is preferable to a census.
- ACost savings
- Btime economy
- Cmore in-depth information
- Dgreat practicality and security
- Eless total error
32A listing of the members of the target population that can be used to create and draw the sample.
- ASampling
- BSampling frame
- CPopulation or universe
- DSample size
33Often this universe is called a target population because of the
importance of focusing on exactly who the study objects are and where they are located.- ASampling frame
- BPopulation or universe
- CSampling
- DSample size
34Consists of obtaining information from a portion of a larger group or population.
- ASampling frame
- BPopulation or universe
- CSampling
- DSample size
35Is introduced into the research results from any source other than sampling.
- ANonsampling error
- BSampling error
- CSample bias
- DSampling frame
36Occurs when the sample does not perfectly represent the population under
study.- ASampling error
- BSample bias
- CNonsampling error
- DProbability bias
37Is introduced into a sample when the sample varies in some systematic way
from the larger population.- ASample bias
- BSampling error
- CNonsampling error
- Dsample frame
38The size of the sample will be a function of the accuracy of the sample.
- ASample size
- BSample frame
- CSampling error
- DProbability error
39Samples where each element has a known chance to be included in the sample.
- AProbability sampling
- BNonprobability sampling
- CSimple random sample
- DStratified sample
40Sampling techniques that do not involve the selection of sample elements by chance.
- AProbability sampling
- BNonprobability sampling
- CStratified sampling
- DSimple random sample
41A technique that allows each element of the population an equal and known chance of being selected as part of the sample.
- ASimple random sample
- BStratified sample
- CCluster sample
- DSystematic sample
42Characterized by the fact that the total population is (1) divided into mutually exclusive subgroups (strata) (different age or income groups and the like) and that
(2) a simple random sample is then chosen from each subgroup.- AStratified sample
- BSystematic sample
- CCluster sample
- DSimple random sample
43The population is divided into mutually exclusive subgroups, and the next step involves the selection of a random sample of subgroups rather than a random sample from each subgroup.
- ACluster sample
- BSimple random sample
- CStratified sample
- DSystematic sample
44Every element has a known but not equal chance of being selected.
- ASystematic sample
- BSimple random sample
- CCluster sample
- DStratified sample
45Any process that quickly and easily selects sample elements.
- AConvenience sample
- BJudgment sample
- CQuota sample
- DCluster Sample
46A subjective approach to sampling, the knowledge and experience of a professional researcher can create a very representative sample.
- ACluster sample
- BJudgment sample
- CQuota sample
- DConvenience sample
47Takes great pains to obtain a representative sample by dividing the population and assigning appropriate quotas based on prior knowledge and understanding of the characteristics of the population.
- AQuota sample
- BConvenience sample
- CCluster sample
- DJudgment sample
48Refers to the strength of a relationship or the magnitude of a difference between two values.
- ASubstantive significance
- BSystematic significance
- CStratified significance
