Glossary
accretion measure. "An unobtrusive measure utilizing deposited physi-
cal material" ( K. D. Bailey, 1978, p. 429; see also Webb et al., 1972).
case record. Condensation of raw data into a manageable, readable pack-
age.
case study. An in-depth study of all pertinent aspects of a person, thing,
situation, institution, community, and so on ( K. D. Bailey, 1978, p. 429;
Good, 1963, p. 388; Mouly, 1970, p. 347).
classical theory building vs. grounded theory building. In classi-
cal theory building, one (1) establishes a concept or proposition; (2) de-
velops hypotheses; and (3) conducts measurements and analyzes to verify
the hypotheses. In grounded theory building, one (1) collects and ana-
lyzes data; (2) considers only those variables and hypotheses that emerge
from the data; and (3) formulates a concept or proposition from the emer-
gent relationships.
closed question. A questionnaire item in which optional response cate-
gories are provided for the respondent ( K. D. Bailey, 1978, pp. 104, 430;
Mouly, 1970, p. 249; Newman, 1976, p. 10).
comparability. The degree to which the ethnographer delineates the con-
structs generated and the characteristics of the groups studied so that
they can be compared to other like and unlike groups ( LeCompte & Goetz,
1982, p. 34; Wolcott, 1973).
concurrent validity. The estimate of how well a test correlates with an-
other test that is considered to be valid.
construct validity. A conglomeration of all other types of validity. (Factor
analysis is also frequently used to estimate construct validity.) The de-
gree to which a test has construct validity is related to how well the test
estimates the psychological construct being measured. Most frequently,
authors refer to construct validity by summarizing several studies that
give supportive evidence.
