This study is an experimental study because it involves investigating a causal relationship between two phenomena. In this study the researcher is investigating the relationship and checking for causality between the size of a group, and its effect on conformity behavior. This study furthermore has an independent variable (i.e. a variable that is manipulated and controlled) which is the size of the group of people staring up at a window.
Answer:
norms
Explanation:
Social norms, or customs, are unwritten behavioral guidelines that are deemed acceptable in a community or culture. These social norms are vital for the stability and predictability of a society. People who follow these norms are well adjusted in group and those who don't follow the norms will be disapproved or even excluded from the group.
