LESSON 8 Flashcards
the ability of the instrument to ‘correctly screen or identify the variables’ to be manipulated
sensitivity
the ability of the instrument to ‘correctly identify non-cases or extraneous variables’ and screen out those condition not necessar
specificity
the ability to ‘identify a case correctly’
sensitivity
the ability to ‘identify a non case correctly’
specificity
to screen in or diagnose ‘a condition correctly’
sensitivity
an instrument yielding TRUE POSITIVES
sensitivity
to screen in or diagnose ‘without the condition correctly’
specificity
an instrument yielding TRUE NEGATIVES
specificity
this takes place when ‘changes in subjects occur during experimental study’
maturation
a pre test is requisite
testing
this refers to ‘the influence to the pre-test’, which already projects the result of the post test scores
testing
the existence of the difference between pre-test and post-test results caused by damage in the accuracy
instrumentation change
this happens when a ‘difference exists between the subject drop out rates’ of either the experimental group and the control group
mortality
the degree to which ‘study results can be influenced or affected by external factors’ or population and settings
external validity
occurs when study participants respond in a particular manner, or there is ‘obvious change of behavior because they are aware that are being observed’
