Hi Dr. Pounds, </div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif;
font-size: 12pt; color: rgb(0, 0, 0);">
I am currently working on the lab report for the Standardization
of NaOH lab, and I am confused as to how we are supposed to
calculate the deviation for the trials. Is there a formula that
does not include the sum (like the standard deviation formula
but without the E...)? </div>

Please let me know if this makes sense or if you would like me
to further clarify my question. </div>

<p>Since we are using such a small sample, the AVERAGE DEVIATION is
the equation you need. You will find it back in the Experiment 1
(Measuring Uncertainty, Density of an Unknown Metal) procedures.</p>
