. single-group validity.
Explanation:
single group validity occurs when the statistical prediction shows different validities for groups such that one group may have something different from zero statistical validity and the other has something different. This is seen in the above example with the men and women group. The statistical prediction for men holds better validity since its prediction is more statistically significant than the women group hence single group validity
Experimental studies manipulate factors to determine their effects.
An experimental study involves manipulating one variable (called an independent variable) to determine its effect on another variable (a dependent variable). An example of a manipulated variable (independent variable) can be hours of sleep, and the dependent variable (resulting variable) can be speed of reflexes. Hours of sleep (independent variable) can be manipulated (increased or decreased) to see the result it has on speed of reflexes (outcome or dependent variable).
