The standard deviation of the numbers 9, 16, 23, 30, 37, 44, and 51 is approximately 14.6. To calculate this, find the mean, calculate each number's deviation from this mean, square these deviations, find the mean of these squares, and take the square root.

FAQs & Answers

  1. What is standard deviation in statistics? Standard deviation measures the amount of variation or dispersion in a set of values, showing how spread out the numbers are from the mean.
  2. How do you calculate standard deviation step-by-step? To calculate standard deviation, find the mean, subtract the mean from each number, square the results, find the mean of these squared differences, and then take the square root.
  3. Why is standard deviation important? Standard deviation helps understand data variability and consistency, which is crucial in fields like finance, science, and quality control.
