explained variance

the proportion of the variance in a dependent variable that can be determined or explained by one or more other variables. In analysis of variance procedures, the explained variance usually is given by eta squared or omega squared, whereas in prediction methods, such as multiple regression, it usually is given by the coefficient of multiple determination. Explained variance also is applied in procedures such as principal components analysis or factor analysis to describe the proportion of the variance in a measure that can be understood or predicted from a component or factor. Compare error variance.

family medicine

the practice of treating a wide variety of illnesses and disorders in individuals and family members of all ages. Physicians now specializing in this area (called family practice doctors) must first undergo special training and become certified or board-eligible in family medicine in order to practice; such requirements did not apply until the 1970s. Family physicians trained before family medicine became a certifiable specialty are usually called general practitioners or GPs (labels sometimes also used by osteopaths). Both types of family physician are considered primary care providers.
