A group of 14 children children received the following scores in a reading test: 35, 35, 26, 26, 26, 29, 29, 29, 12, 25, 25, 25, 25, 17. What was the median score?

The correct answer is B. 26

To find the median score, we first need to arrange the scores in ascending order:

12, 17, 25, 25, 25, 25, 26, 26, 26, 29, 29, 29, 35, 35

Since there are 14 scores, the median will be the average of the 7th and 8th scores in this sorted list. Those scores are both 26.

So, the median score is 26.
