True or False Unstructured Observational Measurement is when the researcher carefully defines what he or she will observe and how the observations are made, recorded, and coded as numbers.
false structured observational measurement
200
The _______ measures pain with facial expressions instead of numbers.
Visual analog scale
200
true or false
the proportion of pts without the disease who have a negative test result or true negative
low: very good at identifying the pts without a disease
high : limited in identifying pts without disease

Punching the wrong key when entering data into the computer is an example of
what is random measurement error
300
focuses on determining whether the instrument measures the theoretical construct that it purports to measure, which involves examining the fit between the conceptual and operational definitions of a variable
what is construct validity
