I only get one value at a time in the system that I am developing. However whenever I get my first value I should already be able to calculate a variance. Every time I get a new value I should recalculate the variance. One important note is that I can't save any previous values, I should thus be able to calculate variances "on the fly".

Something like this is what I would need but for variances.

Thank you
