Reject rate refers to the percentage of items or individuals that are deemed unacceptable or unsatisfactory and therefore not accepted or approved. This can apply to a variety of situations, such as product quality control, job applications, or academic submissions. A high reject rate indicates a high number of rejections, while a low reject rate suggests a high level of acceptance. In business, a high reject rate can lead to financial losses and damage to reputation, while in personal matters, it can cause disappointment and frustration. Overall, reject rate is a measure of the success or failure of a particular process or system in meeting certain standards or criteria.
