D The highest score was in first period.
how is first period scores highter than third period, when third period median was 80
The question does not ask which class had a higher median score. It asks which statement is true based on the information provided about the median and range in each class.
The median and range only provide information about the middle and spread of the scores, respectively. They do not give information about the highest or lowest scores. Therefore, it is possible for the highest score to be in first period (as stated in option D) even if the median score in third period was higher.
