It would decrease.
Step-by-step explanation:
The null almost always acts like a placeholder where there is nothing to record for that entry, we can say that it is a dummy character.
The difference between null and zero is that zero has a value in a context whereas null does not have any value.
So given the example in the question, if we replace the null values with zeros, that would affect the average because of the fact that zero values are going to get included in the average, null values were not included. Therefore this will result in the average being decreased.
