• Standard deviation measures the square root of the variance.

    • What is Standard Deviation?

    Variance and standard deviation are statistical measures used to describe the spread or dispersion of a set of data. Variance measures the average of the squared differences from the mean, while standard deviation measures the square root of the variance. Essentially, it quantifies how spread out the data points are from the mean value. Understanding variance and standard deviation is crucial for making informed decisions, as they provide valuable insights into the reliability of data and the accuracy of predictions.
