Normally your teacher should specify if referring to population vs sample standard deviation. However, in this case, both are the same value. Both are zero.

The standard deviation measures how spread out a set is.
The smallest it can get is 0 which only happens when all values of the set are the same.
Therefore, the standard deviation (both versions) of {7,7,7,7} is 0.

Answer: False
