For five years, Mishra & Koehler conducted an experiment to understand educators’ development of rich technology uses as well as helping them develop their teaching with technology. As a result of this work, they arrived at the Technological, Pedagogical, Content Knowledge (TPCK) model in 2008, later renamed to TPACK.
Conceptual diagram of a simple moderation model in which the effect of the focal antecedent (X) on the outcome (Y) is influenced or dependent on a moderator (W). A statistical diagram of a simple moderation model. Moderation analysis in the behavioral sciences involves the use of linear multiple regression analysis or causal modelling. [1]
Ordinary least squares regression of Okun's law.Since the regression line does not miss any of the points by very much, the R 2 of the regression is relatively high.. In statistics, the coefficient of determination, denoted R 2 or r 2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s).
Henry's [26] proposes an extended model-assisted weighting design-effect measure for single-stage sampling and calibration weight adjustments for a case where = + +, where is a vector of covariates, the model errors are independent, and the estimator of the population total is the general regression estimator (GREG) of Särndal, Swensson, and ...
In this model is the school-specific random effect: it measures the difference between the average score at school and the average score in the entire country. The term W i j {\displaystyle W_{ij}} is the individual-specific random effect, i.e., it's the deviation of the j {\displaystyle j} -th pupil's score from the average for the i ...

The Sobel test is basically a specialized t test that provides a method to determine whether the reduction in the effect of the independent variable, after including the mediator in the model, is a significant reduction and therefore whether the mediation effect is statistically significant.
