Exam 5: Survey Research

Reliability refers to the ______ of a measure,and validity refers to the ______ of a measure.

Stratified random sampling is especially useful when the researcher is interested in

When the distribution of characteristics in a sample is systematically different from that of the target population,the sample is called a

Survey questions that are ordered from the most general to the most specific are

A researcher uses random-digit dialing to conduct a survey using telephone interviews.Suppose that many people don't answer their phone for the survey because when they check the caller identification,they don't recognize the phone number.This represents the potential problem of

In order to assess the test-retest reliability of a measure,the researcher should

A researcher develops a measure of the "self-esteem" construct.One item on the questionnaire states,"I generally feel good about myself." Another item states,"I think I'm not a very good person." The researcher likely uses these two items to protect against possible problems associated with

Internet surveys are best characterized as

A researcher wants to study the developmental changes in social and political attitudes that occur during the time a person is in college.The researcher is interested in both overall trends and in the changes that individual students undergo.Which survey research design will this researcher need to use?

Identify the key features of a good questionnaire item.

A researcher decides to conduct a survey using telephone interviews and has access to random-digit dialing.Because some people have multiple phone numbers and therefore,a greater likelihood of being surveyed,the researcher should be aware of the potential problem of

When a questionnaire item implies a preferred response within the wording of the question,it is called

Suppose a researcher wishes to use stratified random sampling to select a representative sample of 100 people from a population that has the following characteristics: Describe the sample in terms of how many single and married women and men the researcher would need to represent the population.

Distinguish between probability sampling and nonprobability sampling.Name two types of probability samples and one type of nonprobability sample.

Which of the following factors is not likely to increase the reliability of a test or questionnaire?

,separated by six months.At the second testing session she also administered a similar questionnaire called "Nice," which previous research has shown to be a valid measure of people's ability to get along with people and to make friends.She also administered a questionnaire designed to measure art ability,which she predicted to be unrelated to friendliness.She observed the following correlations among the measures: What correlation coefficient value indicates the "Friend" measure has good convergent validity?

The quantitative index of the direction and magnitude of a predictive relationship is called
