The points on the bullseye are measurements whose exact value is the center of the bullseye. Indicate the correct statement: (A). The points of target 3 have clearly less standard deviation than that of target 2. (B). Target 2 points have the worst repeatability of all. (C). The points of target 3 are a set of measurements that lead to a fairly accurate value of the variable, but the instrument cannot be considered very precise. (D). Target 4 points only have systematic errors.
