D) $\sigma ^ { 2 }$

Question

The population variance is represented by. 
A) $S ^ { 2 }$
B) $s ^ { 2 }$
C) $\sigma$
D) $\sigma ^ { 2 }$

Quizplus · Accepted Answer

The population variance is typically denoted by the symbol $\sigma ^ {2}$. Option A ($S^{2}$) is used to represent the sample variance, while option B ($s^{2}$) is also used to represent the sample variance, but in a different notation. Option C ($\sigma$) is the symbol commonly used to represent the population standard deviation. Therefore, the best choice for population variance is option D ($\sigma ^ {2}$).
