If the constant value 5 is added to every score in a distribution with a standard deviation of 4, what is the standard deviation of the new scores?
Answer and explanation
Correct answer: D. 4
- Step 1: Adding a constant shifts the entire distribution without changing the spread or dispersion. Step 2. The standard deviation remains unchanged at 4. Answer: 4. Why not the others: 9 incorrectly adds 5 to the standard deviation.
