What is sx in statistics?

The term "sx" is not a commonly used term or abbreviation in statistics. It is possible that it may refer to the standard deviation of a sample, which is typically denoted as "s." The standard deviation measures the amount of dispersion, or spread, around the mean of a dataset. It is calculated by finding the square root of the variance, which is the average of the squared differences from the mean. The standard deviation is often used to quantify variability and to make inferences about the population from a sample.
