Behv 5622 (module 8)The goal of scientific measurement is to arrive at the best possible _____________ of
the true value of some event that has occurred. - ANS-estimate
________________ values are those values that are recorded from simple observation.
Correct! - ANS-observed
_______________ values are obtained by the investigator by taking special precautions
to minimize or avoid error. - ANS-true
What are the two requirements for evaluating the accuracy of a set of observations? -
ANS-The data must represent physical events, and it must be possible to measure
these events directly.
In order to assess the ______________ of a data set, the observed values are
compared to true values. - ANS-accuracy
_____________________ refers to the consistency of the relationship between
observed values and the events that actually occurred. - ANS-reliability
A measurement procedure is _____________ if it yields the same result every time it is
used to measure the same responses. - ANS-reliable
There are two ways to assess reliability. One way is to repeatedly measure the same
sample of the subject's behavior. What is the second way? - ANS-Compare observed
values to true values.
If accuracy and reliability are both unacceptable, researchers will often evaluate the
data and use their findings to adjust the procedure until the output meets their
standards. This process is known as: - ANS-calibration
When it is not clear that the data represent what they are supposed to represent, the
issue of __________________ arises. - ANS-validity
If the target behavior is directly measured, the data are automatically: - ANS-valid
, When accuracy and reliability are found to be unacceptable, the investigator can either
abandon the project or use ___________________ to evaluate the data and adjust the
procedure so that its output meets desired standards. - ANS-calibration
Interobserver agreement does not provide information about either reliability or
accuracy . - ANS-true
The term ______________ involves convincing others that data are "good enough" for
interpretation. - ANS-believability
While used to enhance the believability of data, ______________________ provides no
information about accuracy or reliability. - ANS-interobserver agreement
The ideal approach to assessing the _________________ of indirect measures involves
finding a way to collect evidence about the relationship between the indirect measures
and what they are intended to represent. - ANS-Validity
__________________ refers to the consistency of the relationship between observed
values and the events that actually occurred. - ANS-reliability
How frequently should data be evaluated? - ANS-Ideally, the investigator should assess
each session, but at least as often as they see necessary based on what the target
behavior is and what the results are showing.
Regardless of whether data assessment focuses on accuracy, reliability, or believability,
there are a number of procedural details that must be decided. All of the following
should be considered when implementing assessment procedures: - ANS--when
assessment efforts should be made
-how frequently data should be evaluated
-sampling different circumstances throughout a study
When reporting complex assessment information, it is sometimes easiest for readers to
understand if it is described using ___________________ instead of described in text: -
ANS-a table or graph
When assessing measurement procedures, what is the first priority? - ANS-determining
accuracy of data
A value that results from observing and recording procedures is called a(n)
__________________ value. - ANS-observed
