What is a Statistics Calculator?
This calculator analyzes a dataset to provide key statistical measures including the mean (average), median, mode, range, standard deviation, and variance. It is ideal for students, researchers, and data analysts.
How to Use This Calculator
- Enter your dataset as a comma-separated or space-separated list of numbers.
- Choose whether the data represents a Population or a Sample (this affects variance and standard deviation calculations).
- Click Calculate to generate the summary statistics.
Formulas
Mean (μ) = Σx / N
Sample Standard Deviation (s) = √[Σ(x - x̄)² / (n - 1)]
Sample Standard Deviation (s) = √[Σ(x - x̄)² / (n - 1)]
Frequently Asked Questions
What is the difference between sample and population standard deviation?
If your data includes every member of the group you are studying, use Population. If your data is only a small representative subset of the whole, use Sample (which uses n-1 in the denominator to correct for bias).
