The 'S' in standard deviation represents the measure of the amount of variation or dispersion in a set of values. A low 'S' indicates that values are close to the mean, while a high 'S' signifies that values are spread out over a wider range.

FAQs & Answers

  1. What is standard deviation used for? Standard deviation is used to quantify the amount of variation or dispersion in a set of data values.
  2. What does a high standard deviation indicate? A high standard deviation indicates that data points are spread out over a wider range of values.
  3. How is standard deviation calculated? Standard deviation is calculated by taking the square root of the variance of a data set.
  4. What is the difference between variance and standard deviation? Variance measures the average degree to which each data point differs from the mean, while standard deviation is the square root of variance.
