These terms are the facilitation value and the discrimination value. 1.        Introduction A.       Facilitation Value : The facilitation value of a question indicates how easy the question is. The facilitation value is calculated by using the following formula. FV= (RU + RL)(2xN*marks of test item) Where N= no. of students in a group. The value is chosen as 30% of the total students from top scorer and 30% of students from low scorers.

So it can be so assumed that the test item was very easy.   When FV=0, means nobody answered the question, it means that either the question was so tough that no one was able to
