What does the sum of squares measure in a dataset?

The sum of squares measures the total variability or dispersion of data points around their mean, quantifying how spread out the values are in a dataset.

Can I use this calculator for large datasets?

Yes, the tool can process multiple numerical values, though very large datasets may be better handled by statistical software for efficiency.

Is the result the same as variance?

The sum of squares is the numerator in the variance formula; dividing by the number of data points gives the variance, but this calculator provides the raw sum of squares figure.

Do I need to calculate the mean first before using this tool?

No, the calculator computes the mean internally as part of the sum of squares calculation process.
