I want to do a survey on cervical cancer which is a KAP study among medical students. But my problem is i can't understand how can i scoring my question like if some students can give 20 correct answer and others can give 10 correct answer. If i use 1 point for each question then someone get 20 and someone get 10 . By this scoring how can i interpret their knowledge about cervical cancer? Or based on my question is it possible to measure their knowledge? And if i want to compare their knowledge among male and female student which measures should i follow? Thank you .
