Learn about two essential tasks in biomedical reasoning: testing logical validity and selecting the right premises to derive conclusions.
answers to one question help us predict how they will answer other questions. If two items are empirically related to each other, we can argue that both items reflect the same concept and we can, therefore, include them in the same index. To determine if your items are empirically related,...
