The symbol for sample standard deviation is s.
This symbol represents the spread or variability of data points within a sample. It is a measure of how much the data points deviate from the sample mean.
Example:
Let's say we have a sample of five numbers: 2, 4, 6, 8, and 10. The sample standard deviation (s) for this data set would be calculated using a specific formula. The result of this calculation would tell us how much the numbers in the sample vary from the sample mean (which is 6 in this case).
Note: The symbol for population standard deviation is σ.
