Greetings Tada Community-

I figured it might be helpful to post a standard deviation (sample method n-1) formula that worked for me.

**Mean Equation Field:** `({Data Point 1}+{Data Point 2})/2`

**Standard Deviation Equation Field:** `(SQRT(POWER({Data Point 1}-{Mean},2)+POWER({Data Point 2}-{Mean},2)/1)`

NOTE: This is using the sample deviation (n-1) method NOT the population deviation method.

Hope it helps some of you.
