In the described method, which action accomplishes the group size measurement?

• A. Sum of the Distances from Each Shot to the Center
• B. Maximum Distance from the Center to Any Shot
• C. Diameter of the Smallest Circle Containing All Shots
• D. Number of Hits Within the Bullseye Zone

Answer: (C)

Group size is about how spread out the hits are. The best way to quantify it is to find the smallest circle that can enclose every shot and then use the circle’s diameter. This captures the outer boundary of the pattern, reflecting the true extent of dispersion since all shots fit inside that circle. Other methods don’t measure spread as reliably: summing distances to the center depends on where the center is chosen and can misrepresent dispersion; looking only at the farthest shot from the center ignores how the rest lie; counting hits in a bullseye zone tells you accuracy to a target area but not how the whole group spreads. So, the diameter of the smallest circle containing all shots is the action that correctly measures group size.
