$s = \frac{\sum (x - \bar{x})^{2}}{n - 1}$
Both a and b
None of the above

The correct answer is: Both a and b

The formula for variance =
$space space space space s squared equals fraction numerator stack sum open parentheses x subscript i minus begin display style x with minus on top end style close parentheses squared with i equals 1 below and n on top over denominator n end fraction rightwards double arrow s equals square root of fraction numerator stack sum open parentheses x subscript i minus begin display style x with minus on top end style close parentheses squared with i equals 1 below and n on top over denominator n end fraction end root$
