what is the meaning of consistency in accounting
Convention of consistency In accounting, the convention of consistency is a principle that the same management accounting principles should be used for preparing financial statements over a number of time periods.[1][2] This enables the management to draw important conclusions regarding the working of the concern over a longer period.[3] It allows a comparison in the performance of different periods. If different accounting procedures and processes are used for preparing financial statements of different years then the results will not be comparable because these will be based on different postulates.
Validity (statistics) Concurrent validity refers to the degree to which the operationalization correlates with other measures of the same construct that are measured at the same time. When the measure is compared to another measure of the same type, they will be related (or correlated). Returning to the selection test example, this would mean that the tests are administered to current employees and then correlated with their scores on performance reviews.
