Methodology Flashcards
Validity
measure what it is intended to
Reliability
likelihood to get the same or similar scores across multiple instances of measurement of some variable.
Inter-rater reliability
describes the situation where the observations produce the same or similar codes and themes within the analysis of qualitative sources of data.
reliability coefficient
reliability associated with quantitative measures is expressed as a decimal,
Construct validity
an instrument measures an intended concept or construct.
content validity
instrument measures the intended subject matter of the content and takes into account all aspects of a situation.
criterion validity
degree that scores on an instrument correlate with scores on a similar instrument measuring the same or similar construct
Stability reliability
represents similar performance when data collection using the instrument occurs on different occasions (separated by an adequate amount of time).
Equivalent (or alternative) forms reliability
involves using forms of the test that contain different versions of the same items with the results on the two forms consistent over time.
Test–retest reliability
represents consistency in scores when respondents complete the test on multiple occasions over a period of time
Face validity
involves the examination of an instrument to determine if it measures what it says it is supposed to.
Convergent validity
focused upon using statistical measures (correlation) to show that your instrument is well aligned with another instrument that has already proven reliable.
anecdotal notes
observations but are usually shorter episodes where the teacher quickly jots a few notes about a student or situation.
observations
record exactly what is happening in a specific context within a specified timeframe.
Interviews
an opportunity to speak with participants directly
