What was the calculator method used for in the $50 Speeding Ticket experiment?

The calculator method in the $50 Speeding Ticket experiment was used to analyze group consensus. This approach involved participants using a calculator to examine their opinions and judgments related to the speeding ticket scenario presented to them. The purpose was to gauge how individuals within a group arrived at a shared understanding or agreement about the issue at hand.

This method facilitated an in-depth exploration of the decision-making process when people were confronted with a common problem. By utilizing a tool that aided in numerical evaluation, researchers could better understand how individuals contribute to and influence collective opinions and perceptions. Hence, this focus on group consensus helps shed light on social influences and dynamics at play in group settings, which aligns with core principles of social psychology.

The other choices pertain to aspects that either do not directly involve the methodology used for analyzing group opinion or fall outside the primary focus of the experiment's objective.
