The formula to calculate the Drop Out Ratio (D) is:
\[ D = \left( \frac{S}{T} \right) \times 100 \]
Where:
The drop out ratio is a metric used to measure the percentage of students who discontinue their education before completing their course of study. It is an important indicator for educational institutions to understand the retention rate and identify potential issues that may be causing students to leave. A high drop out ratio can indicate problems such as lack of student engagement, financial difficulties, or inadequate academic support. Conversely, a low drop out ratio suggests that the institution is successful in retaining its students and providing a supportive learning environment.
Let's say the number of students who dropped out (S) is 20, and the total number of students enrolled (T) is 200. Using the formula:
\[ D = \left( \frac{20}{200} \right) \times 100 = 10 \% \]
So, the drop out ratio (D) is 10%.
