Vocaloid:

neither residual = observed - predicted

Vocaloid:

the y-value of the given point is the "observed" the y-value you get from the equation is the "predicted" so calculate observed - predicted

zarkam21:

D?

zarkam21:

I mean b :/

Vocaloid:

you were right the first time lol

Vocaloid:

8.5 is predicted 7 is observed so 7 - 8.5 = -1.5 = D

zarkam21:
