The sample standard deviation is defined as the root-mean-square of the differences between observations and the sample mean: A significant deviation is defined as two or more standard deviations from the mean.
The lowercase Greek letter (sigma) for the population standard deviation or the Latin letter s for the sample standard deviation is most commonly used in mathematical texts and equations to represent standard deviation.
For example, if the sample variance for a frequency distribution of hourly wages is 10 and the sample standard deviation is $3.16.
Therefore, the sample standard deviation is (B) $3.16.
The complete question is given below: If the sample variance for a frequency distribution consisting of hourly wages was computed to be 10, what is the sample standard deviation?
So, if the first person takes half of the pizza, half of the pizza is left. If the second person takes half of the amount the first person took, that would be a quarter of the pizza left.
