Answer:
The mean and median will change.
Step-by-step explanation:
Mean takes the sum of all the numbers and divide by the amount of numbers there are. This would add 1 to the denominator, which would decrease the total mean score, as the numerator does not change.
The Median will also change. The median is found by finding the middle number of the set. Adding 0 to the set would result in a different number being chose for the median.
