I don't understand what the interval, lower and upper bound outputs for this explorer tool are - they don't seem to match the traditional chi^2 math you would do to calculate the CI of a stdev. "Interval" doesn't even seem to match the range between the upper and lower bound....
What are the units of interval width?
Are they dependent on the value of the standard deviation?
Is it a half width or a full width?
How do I use this to calculate a CI? I know it's not supposed to be symmetrical...
Please and thank you,
