Chance factors: luck in selection of answers by sheer guessing, momentary distractions; The goal of estimating reliability is to determine how much of the variability in test scores is due to measurement errors and how much is due to variability in true scores . [7] A true score is the replicable feature of the concept being measured. It is the ...
Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. [1] Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio.
Accuracy is also used as a statistical measure of how well a binary classification test correctly identifies or excludes a condition. That is, the accuracy is the proportion of correct predictions (both true positives and true negatives) among the total number of cases examined. [10] As such, it compares estimates of pre- and post-test probability.
The Coleman–Liau index is a readability test designed by Meri Coleman and T. L. Liau to gauge the understandability of a text. Like the Flesch–Kincaid Grade Level, Gunning fog index, SMOG index, and Automated Readability Index, its output approximates the U.S. grade level thought necessary to comprehend the text.
A validity scale, in psychological testing, is a scale used in an attempt to measure reliability of responses, for example with the goal of detecting defensiveness, ...
In psychology, interpersonal accuracy (IPA) refers to an individual's ability to make correct inferences about others' internal states, traits, or other personal attributes. [1] For example, a person who is able to correctly recognize emotions, motivation, or thoughts in others demonstrates interpersonal accuracy.
Repeatability or test–retest reliability [1] is the closeness of the agreement between the results of successive measurements of the same measure, when carried out under the same conditions of measurement.
The ASEBA was created by Thomas Achenbach in 1966 as a response to the Diagnostic and Statistical Manual of Mental Disorders (DSM-I). [3] This first edition of the DSM contained information on only 60 disorders; the only two childhood disorders considered were Adjustment Reaction of Childhood and Schizophrenic Reaction, Childhood Type.
