Standard deviation measures how spread out the numbers in a dataset are from the mean. A low standard deviation means data points are close to the mean, while a high standard deviation indicates more variation.

FAQs & Answers

  1. What does a low standard deviation mean? A low standard deviation means that the data points are closely clustered around the mean, indicating less variability in the dataset.
  2. How is standard deviation calculated? Standard deviation is calculated by finding the square root of the average of the squared differences between each data point and the mean.
  3. Why is standard deviation important in statistics? Standard deviation is important because it helps quantify the amount of variation or dispersion in a dataset, which is crucial for data analysis and interpretation.
