Index of discrimination (point biserial)
Formula for index of discrimination
D = no. of correct scores - correct answers
T/F: the higher the discrimination index, the better the item
T
T/F: the positive discrimination index indicates that most low scoring students got the item correctly than high scoring students
F
T/F: negative discrimination index shows that most low scoring students got the item correctly than the high scoring students
T
T/F: if the discrimination index is positive, there is a problem in the item
F
T/F: if the discrimination index is negative, the item is either too hard or poorly written
T
T/F: if the discrimination index is below 0.0, this indicates that there is a problem
T
T/F: if the low ability group got the most correct answers than the high ability group, there is no need to review to options
F
Interpret >,= 0.40 discrimination index
very good
Interpret 0.30-0.39 discrimination index
reasonably good
Interpret 0.20-0.29 discrimination index
marginal items need improvement
Interpret <0.20 discrimination index
Poor, rejected, revised

Selected
What should be the decision for negative and zero discrimination index?
Rejected
What should be the decision for high and low difficulty value items?
Rejected
Identify the term: determines if the students have learned the concept being tested
Index of difficulty (p-value)
Identify the term: measures the percentage of students who get the item correctly
Index of difficulty (p-value)
Identify the term: mean score of each item and the relative frequency of choosing the item correctly
Index of difficulty (p-value)
What is the formula of difficulty index?
Difficulty = (no. of students who answered an item correctly/total no. of student) x 100
What does a higher difficulty index imply?
