Frequently Asked Questions (FAQs)
Population Standard Deviation (σ) uses total population size (N) in denominator, while Sample Standard Deviation (s) uses (N - 1) to account for sample bias (Bessel's correction).
The midpoint (x) for any class interval (e.g., 10 - 20) is calculated by taking the average of lower limit and upper limit: (10 + 20) / 2 = 15.
Geometric Mean (GM) calculates the central tendency using products instead of sums. It is ideal for positive ratios, financial return rates, and percentage growth trends.
You can directly type comma-separated numbers into the screen box or press numerical keys and use the "ADD" button to append entries into your dataset.
Geometric Mean requires taking roots or logarithms of numbers. Logarithms or roots of zero and negative values are mathematically undefined in real number calculations.
