Exam 8: Sampling

The true list of elements in the population is called the:

A good way to avoid sampling bias in the assessment of public opinion about a specific criminal justice topic is to employ the use of a radio call-in show since those who call radio talk shows represent everyone in the population.

An RA at a local university devised a plan to spot check the dorm for illegal drinking by knocking on every 5th door on each floor.What technique was the RA using?

The sampling__________ is the range of sample statistics we would obtain if we selected many samples.

A recent political poll showed that the findings reported were accurate to within 4 percentage points.This is likely to mean what?

Which of the following statements is not accurate with respect to standard error?

The size of the sample and the standard error are related in which of the following ways?

Your criminal justice class requires a study of the success of your state's drug courts.The professor suggests that you first select 10 counties from your state.From those ten counties you will select the two largest cities from each.Finally the drug courts in each of the cities will be monitored to measure success.What type of sampling design did your professor suggest?

Your research methods class has been given the assignment to measure the student body of your university with respect to their attitudes about the death penalty.To ensure equal representation of undergraduates,graduate students and all majors,what sampling technique would you use? How would you go about pulling that sample? What would you need to know before that sample is pulled?

________________sampling is a technique that begins by identifying a single or small number of subjects and asks them to identify others who may be willing to participate.

The correspondence between a target population and sampling frames affects the of the______________ samples.

Which of the following does not illustrate a population where cluster sampling would be the best choice?

Random selection permits the researcher to link findings from a sample to the body of probability theory in order to estimate the accuracy of those findings.

In probability theory,the standard_____________ indicates how closely the sample estimates will be distributed around the population parameter.

Multistage cluster sampling with stratification,systematic sampling,simple random sampling and disproportionate stratified sampling are examples of:

Discuss how the NCVS and The British Crime Survey use different strategies form sampling to produce sufficient numbers of respondents.

When no reasonable sampling frame exists and a probability sample cannot be drawn,at least estimates about the sample accuracy are available through nonprobability samples.

If a researcher has a list of 10,000 elements and wants to sample 1000 and selects every 10th element she is using:

To ensure that variables that occur rarely in a population will be represented in a sample,the researcher would want to employ a ______________sampling technique.

If you did not have the sampling frame of your population but still wanted to use a probability sampling technique for statistical reasons,you should select what type of sample?
