To quickly assess the difficulty of the text, read a short excerpt:
The basic question is how program participants are selected: if they are chosen solely on the basis of group characteristics, then analysis of change scores is appropriate; but if selection is based on individual as well as group differences, then analysis of convariance is necessary. Where the basis for selection is not known presentation of results from both methods of analysis is indicated. One assumption common to both methods is that the earnings (or wages or employment) function does not ...change between the measurement of the pre -and post-training scores: if it does, neither of these methods will be successful. If the function is stable with the exception of the error variance, it may be possible to correct for this shift in reliability (Kenny 1975: 355). Dependent variables . Earnings, wage rates, and labor force participation (hours worked, employment stability, incidence of unemployment) have been the major dependent variables in studies of the effects of training. However, these variables have been measured in different ways: by the absolute post -program level, by the change from the pre -program level, and by the percentage change from the preprogram level.
