Does a standard deviation represent variance in BOTH directions of an AVG, or TOTAL variance...

Example, which one is accurate?

A. Avg=50, SD 30, Range=120-180

B. Avg=150, SD=30, Range=135-165

I know it is a basic picture, but is it close? Statistics class was a while ago...

I would suggest sending a PM to richard157, with that question, he taught math in college.

I really don't know.

I tested every hour for the last 24, because I wasn't sleeping anyway and my fasting numbers have really been high. The average for the 24 hours was 91. But, I had a high of 223 and a low of 61. I did see what I suspected was happening, I go really low about 4:30 and then started going high the rest of the morning. Now just don't know what to do with this information.
