question

Confidence interval
answer

The range of values within which a population parameter is estimated to lie. A survey, for instance, may show that 40 percent of a sample favor a ban on handguns. Although the best estimate of the support that exists among all people is also 40 percent, we do not expect it to be exactly that. We might, therefore, compute a confidence interval (for example, from 35 to 45 percent) within which the actual percentage of the population probably lies. Note that it is necessary to specify a confidence level in connection with every confidence interval.
question

Environmental survey
answer

Structured observations undertaken in the field and recorded on specially designed forms. Note that interview surveys record a respondent’s answers to questions, while environmental surveys record what an observer sees in the field. For example, a community organization may conduct periodic environmental surveys to monitor neighborhood parks–whether facilities are in good condition, how much litter is present, and what kinds of people use the park.
question

Longitudinal study
answer

A study design that involves the collection of data at different points in time, as contrasted to a cross-sectional study. See also trend study, cohort study, and panel study.
question

Reductionism
answer

A fault of some researchers: a strict limitation (reduction) of the kinds of concepts to be considered relevant to the phenomenon under study.
question

Snowball sampling
answer

A method for drawing a nonprobability sample. Snowball samples are often used in field research. Each person interviewed is asked to suggest additional people for interviewing.
question

Stratification
answer

The grouping of the units composing a population into homogeneous groups (or strata) before sampling. This procedure, which may be used in conjunction with simple random, systematic, or cluster sampling, improves the representativeness of a sample, at least in terms of the stratification variables.
