The g factor [a] is a construct developed in psychometric investigations of cognitive abilities and human intelligence.It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks.
A correlation coefficient is a numerical measure of some type of linear correlation, meaning a statistical relationship between two variables. [ a ] The variables may be two columns of a given data set of observations, often called a sample , or two components of a multivariate random variable with a known distribution .
In psychology, association can sometimes be synonymous with correlation. When something is referred to as having positive association or positive correlation, it describes high or low levels of one variable happen with high or low levels of another variable.
PsyCap has positive correlation with desired employee attitudes, behaviors and performance. [9]A meta-analysis of 51 independent samples found strong, significant, positive relationship between PsyCap and desirable attitudes (e.g., satisfaction, commitment, and well-being), behaviors (e.g., citizenship) and performance (self, supervisor rated, and objective) and a negative relationship with ...
In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
Multiple traits are used in this approach to examine (a) similar or (b) dissimilar traits (), in order to establish convergent and discriminant validity between traits. . Similarly, multiple methods are used in this approach to examine the differential effects (or lack thereof) caused by method specific va
The correlation coefficient is +1 in the case of a perfect direct (increasing) linear relationship (correlation), −1 in the case of a perfect inverse (decreasing) linear relationship (anti-correlation), [5] and some value in the open interval (,) in all other cases, indicating the degree of linear dependence between the variables. As it ...
The item–total correlation is the correlation between a scored item and the total test score. It is an item statistic used in psychometric analysis to diagnose assessment items that fail to indicate the underlying psychological trait so that they can be removed or revised.
