than midium(more than 3.28).
2. Making up detailed items and grading seem to be trusted because they had the marks more
than 3.30.
3.The significance level of the relation between items of the evaluation at clinical practice and its grading by t-inspection is p<0.0001 and so it appears to be meaningful.

of the evaluation at clinical practice and its grading.
