FAQs & Answers
- What is standard deviation? Standard deviation is a statistic that measures the dispersion or variation in a set of values.
- Why is standard deviation important? It helps to understand the variability in your data and identify any outliers which may skew your analysis.
- How do you calculate standard deviation? Standard deviation is calculated by finding the square root of the variance, which involves measuring the average distance of each data point from the mean.
- What does a high standard deviation indicate? A high standard deviation indicates that data points are spread out over a wider range of values, often due to outliers.
