The false positive rate (FPR) is the proportion of all negatives that still yield positive test outcomes, i.e., the conditional probability of a positive test result given an event that was not present. The false positive rate is equal to the significance level. The specificity of the test is equal to 1 minus the false positive rate.
Some philosophers (see criticisms) disagree that the negative–positive rights distinction is useful or valid. Under the theory of positive and negative rights, a negative right is a right not to be subjected to an action of another person or group such as a government, usually occurring in the form of abuse or coercion.
As opposed to negative stereotypes, positive stereotypes represent a "positive" evaluation of a group that typically signals an advantage over another group. [2] As such, positive stereotypes may be considered a form of compliment or praise. [3] However, positive stereotypes can have a positive or negative effect on targets of positive stereotypes.
If individuals who have the condition are considered "positive" and those who do not are considered "negative", then sensitivity is a measure of how well a test can identify true positives and specificity is a measure of how well a test can identify true negatives: Sensitivity (true positive rate) is the probability of a positive test result ...
The negativity bias, [1] also known as the negativity effect, is a cognitive bias that, even when positive or neutral things of equal intensity occur, things of a more negative nature (e.g. unpleasant thoughts, emotions, or social interactions; harmful/traumatic events) have a greater effect on one's psychological state and processes than neutral or positive things.
New research on the potential health benefits of fizzy water has revealed some surprising positives - but also some negatives. The study suggests sparkling water could help people lose weight by ...
In statistical hypothesis testing, a type I error, or a false positive, is the rejection of the null hypothesis when it is actually true. A type II error, or a false negative, is the failure to reject a null hypothesis that is actually false. [1] Type I error: an innocent person may be convicted. Type II error: a guilty person may be not convicted.
