"Non-standard" refers to anything that deviates from the usual or accepted norms. This can apply to various fields, such as language, measurements, or practices. For example, in education, non-standard assessments might include alternative methods of evaluating student performance, rather than traditional tests. In the context of mathematics, non-standard can refer to non-standard analysis, which uses hyperreal numbers to provide a rigorous framework for calculus. Similarly, in business, non-standard procedures might involve unique approaches to problem-solving that differ from conventional methods, allowing for innovation and creativity.
