These estimates provide information needed to decide what type(s) of questions and how many of them to use. More true-false questions can be answered during a given period of time than multiple choice or short answer questions. However, our choice of question types must be based on the level of learning at which we are assessing our students. We can decide to use true-false and short-answer questions for the knowledge component, and multiple choice for the comprehension. We will award the lowest number of points per question (1 per question) for the easiest questions (in this case the true-false and short answer). This helps us determine the number of true-false or short answer questions to include, as shown in example 1d.
