### And Furthermore, This Class Is Approximately Useless

today in stats:

prof: ...and if we further approximate this, we see that the variance of this function is roughly, approximately, equal to this ...on average.

student: so the standard deviation of the function is approximately equal to the standard deviation of y times that derivative?

prof: very approximately.

That sounds like stats 241/251, but you're so advanced, numerically speaking, that you must be in a higher level class.

Probably.
