<span>Surface friction is typically the main factor regarding slippage between two objects. If the objects are coarse and not smooth, they will most likely grip and not slip easily. If the objects are smooth, they are more likely to slip. Another factor is whether or not lubricant is involved. Even finely tuned cogs and gears can slip if lubricated in excess.</span>
The correct answer is an experimental study with one independent variable.
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:
The group exposed to Treatment B is the control group.
Explanation:
When conducting experiments, researchers use a control group and an experimental or treatment group. For the experimental group, the independent variable is exposed to changes, while in the control group it isn't. The results of both groups are then compared to measure the influence of the modified variable.
In this case, if the group called Treatment A is the one designated as the treatment group, the Treatment B group must be the control group.
