Precision and recall. In statistical analysis of binary classification and information retrieval systems, the F-score or F-measure is a measure of predictive performance. It is calculated from the precision and recall of the test, where the precision is the number of true positive results divided by the number of all samples predicted to be positive, including those not identified correctly ...
Scores acquired from the F-scale could be directly associated with background components, educational level, and intellectual capacity. [2] It is an indirect type of test that ensures the result would not be due to the individual's fake responses; this is possible because the purpose of the measurement and which attitude is being measured are ...
An F-score is a combination of the precision and the recall, providing a single score. There is a one-parameter family of statistics, with parameter β, which determines the relative weights of precision and recall. The traditional or balanced F-score is the harmonic mean of precision and recall:
For all testing, both diagnoses and screening, there is usually a trade-off between sensitivity and specificity, such that higher sensitivities will mean lower specificities and vice versa. A test which reliably detects the presence of a condition, resulting in a high number of true positives and low number of false negatives, will have a high ...
Cover of Hare's Psychopathy Checklist-Revised (2nd ed., 2003). The Psychopathy Checklist or Hare Psychopathy Checklist-Revised, now the Psychopathy Checklist—revised (PCL-R), is a psychological assessment tool that is commonly used to assess the presence and extent of psychopathy in individuals—most often those institutionalized in the criminal justice system—and to differentiate those ...
F1 score is even more unreliable in such cases, and here would yield over 97.4%, whereas informedness removes such bias and yields 0 as the probability of an informed decision for any form of guessing (here always guessing cancer).

Disclosure is the only score in the MCMI-IV in which the raw scores are interpreted and in which a particularly low score is clinically relevant. A raw score above 114 or below 7 [13] is considered not to be an accurate representation of the patient's personality style as they either over-or under-disclosed and may indicate questionable results.
