Answer:




The absolute difference is:

If we find the % of change respect the before case we have this:

So then is a big change.
Step-by-step explanation:
The subindex B is for the before case and the subindex A is for the after case
Before case (with 500)
For this case we have the following dataset:
500 200 250 275 300
We can calculate the mean with the following formula:

And the sample deviation with the following formula:

After case (With -500 instead of 500)
For this case we have the following dataset:
-500 200 250 275 300
We can calculate the mean with the following formula:

And the sample deviation with the following formula:

And as we can see we have a significant change between the two values for the two cases.
The absolute difference is:

If we find the % of change respect the before case we have this:

So then is a big change.
