      • Standard deviation measures the spread of data from the mean, while variance measures the average squared differences from the mean.

      While standard deviation and variance can be used for skewed distributions, they may not accurately reflect the true spread of data. In such cases, it's better to use alternative measures like the interquartile range or the median absolute deviation.

        • Common questions

        Let's start with the basics. Standard deviation and variance are two related but distinct statistical measures that help describe the spread or dispersion of data within a population. Variance measures the average squared differences from the mean, while standard deviation measures the square root of the variance. To illustrate the difference, imagine a set of exam scores. Variance would give you the average squared differences from the mean score, while standard deviation would give you the average distance from the mean score.
