      Sample standard deviation can be used with any type of data, including numerical, categorical, and ordinal data. However, the calculation may vary depending on the type of data.

      In simple terms, sample standard deviation is a measure of the spread or dispersion of a set of data. It represents how much individual data points deviate from the mean value. A low standard deviation indicates that the data points are close to the mean, while a high standard deviation indicates that they are more spread out. To calculate the sample standard deviation, you need to follow these steps:
