Quizplus · Accepted Answer

The population standard deviation is conventionally represented by the symbol $\sigma$, and option A presents this symbol. Option B represents the population variance, which is denoted by $\sigma ^ { 2 }$, and option C represents the sample standard deviation, which is denoted by s. Option D is an unclear representation of the sample standard deviation, as the symbol s by itself is often used to represent other statistics such as the sample variance or sum of squares.
