Rigour In Research Flashcards
Rigour
Striving for excellence and research, using discipline, scrupulous, adherence to detail, and strict accuracy
Reliability
The extent to which the instrument yields the same results on repeated measures
Consistency
Produce the same results if the behaviour is measured again by the same scale
Accuracy
State of being correct, measuring the concept of variable being investigated
Precision
Quality and measurement that is refined and careful
Stability
When they repeated administration of the instrument gives the same results
Homogeneity
The items in the instrument measure the same concept, variable or characteristic
Equivalence
If the instrument produces the same results when compared to a parallel or equivalent instrument
Reliability coefficients
A measure of the accuracy of a test which is obtained by measuring the same individuals twice and computing the correlation of the two sets of measures
Correlation coefficient
Statistical relationship between two variables that range from 1.0 (perfect relationship) to 0.0 (no relationship)
Test-retest reliability
The stability of scores of the instrument when it is administered more than once to the same participants under similar conditions
Cronbach alpha
How closely the related set of items are as a group, measure of scale reliability
Content validity
The degree to which the content being measured represents the whole of the construct
Criterion related validity
The degree of the relationship between the participants performance on the tool and the participants actual behaviour
Construct validity
Examines the fit between conceptual and operational definitions of variables and determines whether or not the instrument measures the theoretical construct that it purports to measure
