What is the p-value of a question? What exactly is the p-value of a question? Converted into a percentage (* 100), the p-value indicates the percentage of candidates who answered the item correctly. A high p-value means that the question is relatively easy and almost every candidate answered it correctly. A low p-value means that the question was too difficult. In that case, the proportion of candidates who answered the question correctly is too low. What is a good p-value? If you have a good test If you want to create a good balance between the question types. A test should not be too difficult, but also not too easy. A good p-value varies depending on the number of possible answers. You can use the table below as a guideline: What is a good p-value? Calculate the P-value of a question Suppose you have a question in your test that you administer to 100 students. You perform a statistical analysis by calculating the number of correct answers. Suppose that 60% of the candidates answered the question correctly, then there is a p-value of 0.60. Want to know more?
