the Standard Deviation</a>

<p>
            Once you have calculated the standard deviation for your data, a legitimate
            question to ask is "How reliable is the calculated standard deviation?".
            For this situation the Chi Squared distribution can be used to calculate
            confidence intervals for the standard deviation.
