Reliability
"the consistency of a measure" (Jhangiani et al.)
What is Reliability?
"the extent to which the scores from a measure represent the variable they are intended to" (Jhangiani et al.)
What is Validity?
"the process of developing indicators" (Bhattacherjee, 2012)
What is Operationalization?
The Central Tendency for the Nominal Scale. (Bhattacherjee, 2012)
What is Mode?
"Describes a particular level, frequency or degree of a single variable. (Slattery, 2023).
What is Frequency claims?
"requires using the measure on a group of people at one time, using it again on the same group of people at a later time, and then looking at the test-retest correlation between the two sets of scores" (Jhangiani et al.)
What is the test-retest reliability?
"the extent to which a measurement method appears “on its face” to measure the construct of interest" (Jhangiani et al.)
What is Face Validity?
"The combination of indicators at the empirical level
representing a given construct" (Bhattacherjee, 2012)
What is a Variable?
The central tendency for Ordinal scales. (Bhattacherjee, 2012)
What is Median?
"argues that one level of a variable is associated with another variable" (Slattery, 2023).
What is association claims?
"the extent to which different observers are consistent in their judgments" (Jhangiani et al.)
What is Inter-radar reliability?
"the extent to which a measure “covers” the construct of interest" (Jhangiani et al.)
What is content validity?
"a measure that 'reflects' an underlying construct" (Bhattacherjee, 2012)
What is a reflective indicator?
The Centraal Tendencies for Interval scales. (Bhattacherjee, 2012)
What is Arithmetic mean, range, standard deviation?
"argues that one variable causes changes in the level of another variable" (Slattery, 2023).
What is Causal Claims?
"the consistency of people’s responses across the items on a multiple-item measure" (Jhangiani et al.)
What is Internal Consistency?
"he extent to which people’s scores on a measure are correlated with other variables (known as criteria) that one would expect them to be correlated with" (Jhangiani et al.)
what is Criterion Validity?
"a measure that 'forms' or contributes to an
underlying construct" (Bhattacherjee, 2012)
What is a formative indicator?
The central tendencies for Ratio scales. (Bhattacherjee, 2012)
What is Geometric mean,
harmonic mean?
"the criterion is measured at some point in the future after the construct has been measured" (Jhangiani et al.)
What is Predictive Validity?
What correlation includes, "splitting the items into two sets, such as the first and second halves of the items or the even- and odd-numbered items" (Jhangiani et al.)
What is split correlation?
"any variable that one has reason to think should be correlated with the construct being measured, and there will usually be many of them" (Jhangiani et al.)
What is Criterion?
"items for measuring construct" (Bhattacherjee, 2012)
What is an indicator?
The statistics used for nominal scales. (Bhattacherjee, 2012)
What is Chi-Square?
"the extent to which scores on a measure are not correlated with measures of variables that are conceptually distinct" (Jhangiani et al.)
What is discriminant validity?
