Answer:
multiply by 25 also.
Step-by-step explanation:
If the scores are multiplied by 25, that means that the mean will also multiply by 25. Since the mean and the scores all increased by 25 times, the standard deviation will increase by 25 times.
If instead, you added 25 (or any other number) to each score, then the standard deviation would not change. The mean and each score will increase by 25, bu the difference between them will not change.
Multi ting a number is like adding the number that many times.
Repeated addition would be adding 3/4 to itself 4 times:
3/4 + 3/4 + 3/4 + 3/4 = 12/4 = 3
Then multiplication method:
3/4 x 4 = 12/4 = 3
