      Q: Can standard deviation be negative?

      Standard deviation measures the amount of variation or dispersion of a set of values. It represents how spread out the values are from the mean (average). Think of standard deviation like a ruler that helps you understand how consistent or inconsistent a set of data is. To calculate standard deviation, you'll need to follow these steps:
