Sample standard deviation is a measure of how spread out a set of data is. It is calculated by finding the standard deviation of a sample of the data, rather than the entire population. This can be useful when the population is too large to measure directly, or when it is not possible to obtain data from the entire population.
The sample standard deviation can be calculated using a TI-84 calculator. To do this, enter the data into the calculator and then press the “STAT” button. Then, use the arrow keys to scroll down to the “CALC” menu and select the “1-Var Stats” option. The calculator will then display the sample standard deviation, along with other statistics such as the mean, median, and quartiles.
