    What is a Low Standard Deviation?

      Standard deviation is a measure of the amount of variation or dispersion from the average value. It represents how spread out the data is, giving an idea of the reliability of the mean value. Imagine you have a set of exam scores, and the average score is 80. If the standard deviation is high, it means that scores are all over the place, making it difficult to predict an individual's score. On the other hand, a low standard deviation indicates that scores are clustered around the average, making predictions more reliable.
