Which function on the stats command allows you to return the sample standard deviation of a field?

The sample standard deviation of a field can be calculated using the "stdev" function within the stats command in Splunk. This function provides a measure of the amount of variation or dispersion in a set of values. Specifically, the sample standard deviation calculates how much the values in a data sample deviate from the mean of that sample. By utilizing "stdev," users can effectively analyze the variability in their data, which is crucial for understanding trends and making data-driven decisions.

While there are other options listed, they do not correspond to the appropriate function for calculating sample standard deviation in Splunk's stats command. For instance, "dev" is a different term that could be associated with other metrics or functions but does not directly yield the sample standard deviation. Other combinations like "count deviation" and "by standarddev" either do not pertain to calculating standard deviation or are not valid functions within the context of the stats command. Thus, "stdev" is the correct choice for obtaining the sample standard deviation of a field in Splunk.
