How to approx. bias in real learning scenarios?

Hi,
I have a basic question i.e In real learning situations,we wont have many datasets to calculate average hypothesis but only one. So how can we calculate bias and variance in real life learning cases??

thanks

In general, we can't. Bias and variance are theoretical tools for illustrating the tradeoff between approximation and generalization.
