Sample Variance Calculator: For Accurate and Immediate Results

What is a Sample Variance?

A sample variance reflects the average of squared deviations from the mean value. Sample variance could also be defined as the recurrence of particular data values with reference to the mean for a single sample population.

Sample variance in statistics can be evaluated through the following formulas (s²):

s² = ∑(xᵢ − x̄)² / (n − 1)

Where:

• s² = Sample variance
• xᵢ = Each data value
• x̄ = Mean of the Sample
• n = Number of observations in the data

Common Questions Received (CQR)

1. What is the difference between sample variance and population variance?

Sample variance (s²) calculation is with n-1 in the denominator as it is a subset of the figure.

Population variance (σ²) calculation is with n in the denominator and it applies to an entire population.

2. Why do we utilize (n-1) in sample variance?

That is called Besselʹs correction which removes the bias of using small samples and allows more accurate estimating of variance.

3. Can the Sample Variance Calculator be used for large data?

Of course! The calculator works for both large and small datasets without any problems.

4. Is the Sample Variance Calculator charged for usage?

Yes! Sample Variance Calculator from Calculator3.com has no fees and can be used anytime.
