Abstract
A test is an observation that is used to classify the elements of a group into different subgroups. The categories derived from such an observation may be construed as an inherent property of the group or class to which the test is applied. On the other hand, since tests consist of specific collections of rules, it could be argued that the resulting categories are ‘by-products’ of the deployment of test instruments on a class. In general, the results of measurement depend on the conditions in which the measurement takes place. These conditions include the instruments used in measurement. It is therefore paramount to evaluate the general and particular characteristics of these tools.
