Standard deviation measures the amount of variation or dispersion of a set of values. For the numbers 6, 8, 10, 12, and 14, the standard deviation is calculated as follows: find the mean (10), subtract the mean from each number, square the result, find the mean of these squares, and take the square root. The standard deviation is approximately 2.83.

FAQs & Answers

  1. What is standard deviation? Standard deviation is a measure of the amount of variation or dispersion in a set of numerical values.
  2. How do you calculate standard deviation? Calculate the mean of the data set, find the squared differences from the mean, take the average of these squared differences, then find the square root of that average.
  3. Why is standard deviation important? Standard deviation helps to understand how spread out the values in a data set are, which is crucial for data analysis and interpretation.
