Frequently Asked Questions
How does this calculator work?
Enter your dataset as comma-separated values, and the calculator computes comprehensive descriptive statistics including central tendency, variability, and distribution shape measures.
What inputs are required?
A dataset of numerical values separated by commas. Minimum 2 values required, but more data points provide better statistical insights.
What statistics are calculated?
Mean, median, mode, range, standard deviation, variance, quartiles, IQR, skewness, kurtosis, and basic descriptive measures.
How do I interpret skewness and kurtosis?
Skewness measures asymmetry: positive = right-skewed, negative = left-skewed. Kurtosis measures tail heaviness: positive = heavy tails, negative = light tails.
What's the difference between population and sample statistics?
This calculator uses sample statistics (n-1 in denominator for variance/std dev) which provides unbiased estimates for sample data.
When should I use median vs mean?
Use median for skewed data or when outliers are present. Use mean for normally distributed data without extreme values.
Can I use this for quality control?
Yes! The calculator is perfect for process monitoring, quality assurance, and identifying data patterns in manufacturing or service processes.
