Improving & Assessing the Quality of Behavioral Management Flashcards
validity
measurement has____ when it yields data that are directly relevant to the phenomenon measured and the reason for measureing
accuracy
to the extent to which the observed value matches the true state
observed value
the quantitative label produced by measuring an event
true value
a measure obtained by procedures that are independent of and different from the procedures that produced the data. Taken all possible efforts to make sure errors are avoided or removed.
measurement bias
nonrandom measurement error
-error in measurement that is likely to be in one direction
reliablility
measurement procedure yields the same value when brought into repeated contact then the same state of nature
direct measurement
occurs when the phenomenon that is the focus of the experiment in the same as the phenomenon being measured
indirect measurement
occurs when what is actually measured is in some way different from the target BX of interest
continuous measurement
measurement conducted in a manner such that all instances of the response class of interest are detected during an observation
discontinous measurement
any form of measurement in which some instances of the response class of interest may not be detected
observer drift
observes alter, unknowingly the way they apply a measurement system
naive observer
a trained observer who is unaware of the study’s purpose and/or the experimental conditions in effect during or given phase or observation period
observer reactivity
measurement error resulting from an observers awareness that others are evaluating the data he reports.
calibration
when measurement error is consistent in direction and value, the data can be adjusted to compensate for the error
interobserver agreement (IOA)
refers to the degree to which 2 or more independent observers report the same observed values after measuring the same events.
