Standard deviation of 0.3 indicates that the data points tend to deviate from the mean by an average of 0.3 units. This small value suggests that the data points are closely clustered around the mean, signifying lower variability in the dataset.

FAQs & Answers

  1. What does a low standard deviation indicate? A low standard deviation indicates that the data points are close to the mean, signifying lower variability in the dataset.
  2. How is standard deviation calculated? Standard deviation is calculated using the square root of the variance, which measures the spread of data points from the mean.
  3. What is the significance of standard deviation in statistics? Standard deviation helps to understand the dispersion of data points in a dataset, crucial for statistical analyses and hypothesis testing.
