idsortelemzések
I sort elemzések, often translated as "element analysis" or "item analysis," is a statistical procedure used in test development and educational measurement to evaluate the quality of individual test items. This analysis helps determine if a question effectively differentiates between test-takers who have a good understanding of the material and those who do not. The core of idsorelemzések involves examining two key statistics for each item: the item difficulty and the item discrimination.
Item difficulty, often represented by a p-value, indicates the proportion of test-takers who answered the item
Item discrimination, on the other hand, measures how well an item distinguishes between high-scoring and low-scoring
