Identify and explain the criteria for retaining and dropping items to revise a test. Make a matrix with faked data for five items. Explain why each item should or should not be retained.
What will be an ideal response?
• p (difficulty) values between .2 and .9
• Large positive discrimination index (D)
• Positive interitem correlation coefficients and item–total correlations suggesting that the item is measuring the same construct as are other items—evidence of internal consistency. The best items will have higher positive correlation coefficients.
• Positive item-total correlations suggesting that the item discriminates between high and low ability test takers
• No evidence of item bias
