When the scores for a recent Chemistry exam were calculated, the mean was 60 and the median was 65. Later the professor discovered that one score had been recorded incorrectly; it had been entered into the computer as a 5, instead of as a 50. When this correction is made, .

Mean of the exam scores will change but median will remain the same.

Step-by-step explanation:

To solve this question we have to understand the difference in mean and median of any set of data.

Mean is simply an arithmetic mean of the data.

If the set of data is 1, 2, 3, 4, 5, 6, 7

Then mean of this data =

                                       =

                                       =

                                       = 4

Median is the middle term which separates higher half of the sample from the lower half.

So median of the given data set = 4

Which is at the center.

Now the mean of the Chemistry score is 60 which will definitely change if any number in the total of the data set changes.

Which means average will change with the change of a number in the set.

But Middle term or median of the set will never change unless we add a new number in the set.

Therefore, answer will be "mean of the exam scores will change but median will remain the same."
