Questions and Answers
Validity - Correct Answer✔️✔️-Do data meaningfully reflect the original reason for
measuring the data?
Valid measurement (3 elements) - Correct Answer✔️✔️-1. direct measurement of
behavior
2. measurement of the dimension (rate)
3. Measurement of the behavior during times and locations relevant to the current
question
Accuracy - Correct Answer✔️✔️-The extent to which the observed value matches the true
state or true value of the event
True Value - Correct Answer✔️✔️-A measure accepted as a quantitative description of
the true state of some dimensional quantity of an event as it exists in nature
Inaccurate measurement renders - Correct Answer✔️✔️-invalid data obtained by
otherwise valid data... likely to over or under estimate true value
nonrandom measurement error - Correct Answer✔️✔️-measurement bias
Reliability - Correct Answer✔️✔️-are data consistent across multiple time points

Reliable measurement - Correct Answer✔️✔️-measurement produces results consistently
and repeated results ( can be across data points, raters, and locations)
In order for data to be trustworthy, measurement must be .. - Correct Answer✔️✔️-both
valid and accurate
Threats to validity (3 main ones discussed) - Correct Answer✔️✔️-1. indirect
measurement
2. Measuring wrong dimension of behavior
3. measurement artifacts
Threat to validity: Indirect measurement - Correct Answer✔️✔️-what is measured is in
some way different than target behavior
ex. student self report and achievement tests
Threat to validity: Measuring wrong dimension of behavior - Correct Answer✔️✔️-be sure
your measurement system aligns with target behavior
ex. gilbert will comply with direction within 5 seconds of being delivered by
teacher...LATENCY
Threats to Validity Measurement artificats - Correct Answer✔️✔️-validity is reduced when
data is misleading because of the way it is measured
Common causes: discontinuous measurement, poorly scheduled measurement periods,
and insensitive and/or limited measurement scales
Threats to accuracy and reliability #1 error - Correct Answer✔️✔️-human error
2/5
