Ch. 4 Vocab Flashcards
(35 cards)
a form of probability sampling in which a researcher samples entire clusters, or naturally occurring groups, that exist within the population
cluster sampling
a system for quantifying responses to open-ended questions by categorizing them according to objective rules or guidelines
content analysis
effects produced by the position of a question; where it falls within the question order can influence how the question is interpreted
context effects
the concept that traits, attitudes, and preferences can be viewed as a continuous dimension, and each individual can fall at any point along each dimension; for ex. sociability can be viewed as a continuous dimension ranging from very unsociable to very sociable
continuous dimension
obtained by using any groups who happen to be convenient; considered a weak form of sampling because the researcher exercises no control over the representiveness of the sample
convenience sampling
the measure of magnitude, or quantitative size, having equal intervals between values but no true zero point
interval scale
the “hidden meaning” behind a question
latent content
the type of scale of measurement - ratio, interval, ordinal, or nominal - used to measure a variable
level of measurement
the plain meaning of words or questions that actually appear on the page
manifest content
people who are apt to disagree with a question regardless of its manifest content
nay-sayers
the simplest level of measurement; classifies items into two or more distinct categories on the basis of some common feature
nominal scale
sampling procedures in which subjects are not chosen at random; two common examples are quota and convenience samples
nonprobability sampling
a measure of magnitude in which each value is measured in the form of ranks
ordinal scale
all people, animals, or objects that have at least one characteristic in common
population
when in doubt about answers to multiple-choice questions, some people always select a response in a certain position, such as answer “c”
position preference
selecting samples in such a way that the odds of any subject being selected for the study are known or can be calculated
probability sampling
the selection of nonrandom samples that reflect a specific purpose of the study
purposive sampling
selecting samples through predetermined quotas that are intended to reflect the makeup of the population; they can reflect the proportions of important population subgroups, but the particular individuals are not selected at random
quota sampling
a table of numbers generate by a computer so that every number has an equal chance of being selected for each position in the table
random number table
an unbiased method for selecting subjects in such a way that each member of the population has an equal opportunity to be selected, and the outcome cannot be predicted ahead of time by any known law
random selection
a measure of magnitude having equal intervals between values and having an absolute zero point
ratio scale
the extent to which a survey is consistent and repeatable
reliability
the extent to which the sample responses we observe and measure reflect those we would obtain if we could sample the entire population
representativeness
a tendency to answer questions based on their latent content with the goal of creating a certain impression of ourselves
response set
