sample standard deviation in a sentence

Examples

2. A simple example is the process of dividing a sample mean by the sample standard deviation when data arise from a location-scale family.
3. The sample standard deviation s = 10.23 is greater than the true population standard deviation " ? " = 9.27 years.
4. The sample standard deviations are still 15.81 and 28.46, respectively, because the standard deviation is not affected by a constant offset.
