Groom and Nass write that in controlled environments, robots in human-like social roles are demonstrating great promise.
Option: 4
Explanation:
Murphy in 2004 studied robotic activities from two different perspectives. One is from controlled environment and another is from unpredictable environment. During the period of application robots are operated by human action. Robots are adaptable to logical explanations.
In controlled environments (Murphy, 2004) robots in human like social roles are demonstrating great promise. To determine who is superior among robot team mates and human team mates one has to fixed the purpose of activity and group first.
Answer:
An observational study of an association between two variables.
Explanation:
In the given scenario, it is an observational study of an association between two variables. The variables being :
- Explanatory variable (independant variable / predictor variable) may explain or influence changes in a response variable.
- Response variable (dependant variable) measures an outcome of a study.
Observational study observes individuals and records variables but doesn't attempt to influence the response (does not impose a treatment). It allows the researcher to directly observed the behavior of inteest rather than rely on the subject's self-descriptions (Survey) thus allowing the researcher to study the subject in its natural environment, thus removing the potentiallybased effect of the unnatural laboratory setting on the subject's performance.
