The Completion Ratio is a metric used to measure the efficiency of a process or project. It is calculated by dividing the number of completed tasks by the total number of tasks, then multiplying by 100 to get a percentage. A higher completion ratio indicates better performance and successful task management. In various fields, such as project management and education, the completion ratio helps assess progress and identify areas for improvement. For example, in online courses, instructors may use this ratio to evaluate student engagement and course effectiveness, guiding adjustments to enhance learning outcomes.
