Change in Median Score

A statistics teacher is analyzing the scores of her class on a recent exam. The scores (out of 100) are as follows: 62, 75, 88, 90, 70, 85, 95, 80, 55, 70. The teacher calculated the mean and median of the scores.

To expand her analysis, she added one more score, 100, to the dataset and recalculated the mean and median. Now she wants to determine how much the median score changed after adding the new score.

What is the change in the median score after the addition of the new score?
