Exam 14: Sampling Fundamentals

In international marketing research, non-probability sampling methods are more frequently used than probability sampling methods.

One way to stratify in a shopping center intercept study is by time segments.

Systematic sampling is useful in sampling time periods.

A researcher who is faced with the problem of non-response can attempt to reduce the potential bias of the results by

In simple random sampling, each population member has an equal probability of being selected.

Which of the following sampling techniques employs both probability and non-probability sampling in selecting study objects ? a) multi-stage sampling b) double sampling c) sequential sampling d) snowball sampling

Ronny Reagy divides the population of the purchaser of missile X into heavy and light users and then he samples from those groups.This is an example of ___________ sampling. a) cluster b) random c) judgmental d) stratified e) quota

Sources of possible shopping center biases include

In a shopping center intercept study, the location used to intercept shoppers can affect the sample.

Most of the marketing research projects employ traditional research methods with replacement.

A researcher is doing a study on champagne consumption.She has defined three different income groups and has assigned interviewers a specific number of interviews with respondents in each group.This is an example of

A researcher's decision on a sampling unit may depend on how purchase decisions are made.

"Heterogeneity within and homogeneity between" is the ideal state for a) cluster sampling b) stratified sampling c) disproportionate sampling d) judgmental sampling e) a and b

Systematic sampling involves systematically spreading the sample through the list of population members.

Linda Evans wants to do a study involving the population of Houston.She, therefore, divided the city into homogenous areas at random and drew a sample of 10 areas where she interviewed all households.This is an example of a) stratified sampling b) cluster sampling c) judgmental sampling d) multiplicity sampling. e) systematic sampling

Systematic sampling involves systematically spreading the sample through a list of population members.

Compared to simple random sampling, the precision of systematic sampling from a sampling frame monotonically ordered on a variable related to the dependant variable is a) the same b) greater c) less d) cannot tell

Probability sampling involves which of the following should be considered? a) the target populations should be specified b) the method for sample selection c) sample size determination d) nonresponse problem e) all of the above

Sampling error is the difference in value between the population parameter and the sample statistic that occurs because of sampling.

Selection of every tenth subscriber to the New York Times is an example of
