Discriminative validity of selected measures for differentiating normal from aphasic performance. Before administering the supplemental section of the WAB-R, the examiner must see the clients performance on the previous Reading and Writing tasks. A correlation can be positive (as one variable increases, the other also increases for example height and weight typically represent a positive correlation) or negative (as one variable increases, the other decreases for example as the cost of gasoline goes higher, the number of miles driven decreases. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. There were excellent correlations between the K-BNT score and K-WAB Object Naming (r=0.720) and Word Fluency (r=0.613) tasks and Naming subtotal score (r=0.719). Part 1 of the WAB takes approximately 30-45 minutes; Part 2 takes approximately 45-60 minutes to administer.

Each subtest score is a portion of the total score according to their respective maximum scores, as follows: Accordingly, the LQ is calculated as the sum of each subtest revised score. This method of evaluating reliability is appropriate only if the phenomenon that the scale measures is known to be stable over the interval between assessments. Internal consistency coefficients can take on values from 0 to 1. Shewan and Kertesz (1980) examined known-group validityThe degree to which an assessment measures what it is supposed to measure.
