If a​ rifleman's gunsight is adjusted correctly but he has shaky​ arms, he might shoot bullets scattered widely around the​ bull's-eye target. Draw a sketch of the target with the bullet holes. Does this show variation​ (lack of​ precision) or​ bias? b. Draw a second sketch of the target if the shots are both unbiased and precise​ (have little​ variation). The​ rifleman's aim is not​ perfect, so your sketches should show more than one bullet hole.
