When formulating a goal programming model, the decision maker will use constraints similar to those used in regular linear or nonlinear programming models. In goal programming models, these constraints are known deviational constraints

ZMET is a projective hypothesis that as part of its visual research technique requires the participant to construct a "mini-movie" that string together the images they have been discussing and describes how they feel about the topic of interest.

a. true b. false

Assume that for a data field, only the codes 1 or 2 should appear. If a researcher mistakenly inputs any other number (say, 3), an error message is immediately displayed on the screen. This indicates that the software being used for data entry probably has a(n):

a. data input detection system. b. input error capture mechanism. c. error edit routine. d. catch-error template. e. outlier detection routine
