GRIMMER (Granularity-Related Inconsistency of Means Mapped to Error Repeats) builds upon the GRIM test and allows for testing whether reported measures of variability are mathematically possible. GRIMMER relies upon the statistical phenomenon that variances display a simple repetitive pattern when the data...
or the degree to which an instrument measures the same way each time it is used under the same condition with the same subjects. In short, it is the repeatability of your measurement. A measure is considered reliable if a person's score on the same test given twice is similar. It is ...
We report a study testing the validity of the three most commonly used indicators of lifetime exposure to print fiction, namely a self-report scale, an author recognition test (ART), and book counting, in a sample of older adults (N=306;Mage = 59.29 years,SDage = 7.01). Conve...
Wearable sensors, such as Inertial Measurement Units (IMUs), may enable the assessment of movement patterns during functional activities in a real-world setting. IMUs usually contain a 3-axis accelerometer to measure linear accelerations, a 3-axis gyroscope to measure angular velocities, as well ...
Information validity refers to"critical point" that decides information creation or effect loss and effect characters(nature and state),that is,the "degree" or "propriety" of information effect.In the related information practices,well recognized and controlled information validity means a good understan...
Bachelor,A P. - 《Educational & Psychological Measurement》 被引量: 6发表: 1989年 A comparison of the validity of the Demirjian, Willems, Nolla and Hvikko methods in determination of chronological age of 5-15 year-old Indian children Background Demirjian's method has been the most popular ...
marketing and other social sciences disciplines, since we establish a new standard means of assessing discriminant validity as part of measurement model evaluation in variance-based SEM. Traditional discriminant validity assessment methods Comparing average communality and shared variance...
This comprises the first two steps in measurement and provides the means for relating the theoretical definitions of the construct to observations of behavior — scores on language test. Evidence supporting validity Content relevance and content coverage Analysis of the internal structure of the test ...
