- (1) Arguments. We don't state that the numbers should be real. How does this function handle arguments that don't correspond to real numbers?
- (2) Additional details. I get a bit confused by this notation; the use of “n” seems unnecessary. I would put “i=0” at the bottom of the summation and use subscript “i” on the x. In the following text I would simply say that “a is the mean value of the numbers and xi are the numbers" (with the i after the x subscripted).
