Answer

Brief Explanations:

  1. Standard deviation measures data - spread.
  2. It is the square - root of variance.
  3. A low value indicates data is clustered around the mean.
  4. A high value means data is more dispersed.
  5. Outliers can greatly affect it as they increase the spread. An outlier will increase the standard deviation of a data set because it is a value far from the mean, which increases the sum of squared differences in the standard - deviation formula.

Answer:

  1. Standard deviation measures the spread of a data - set.
  2. It is the square root of the variance.
  3. A small standard deviation implies data is clustered near the mean.
  4. A large standard deviation implies data is more spread out.
  5. Outliers tend to increase the standard deviation.
