In both inference and observation, you have to monitor or observe something.
Here's one example, you can build on it:
Sherlock Holmes 'observed' the scene below him.
His 'inference' was based on the evidences given to him.
Here's the definition of both of them...
the action or process of closely observing or monitoring something or someone is called observation.
a conclusion reached on the basis of evidence and reasoning is inference.
Catherine's desire to change her name to "Cathy" because that name is easier to say and more like the names of her friends is an example of "social facilitation." Social facilitation, as a phenomena, refers to the tendency of people to act and perform different when others are around as compared to when they are alone. Catherine is comfortable with her proper, original name but decides to change it in order to fit in with other people, which is an example of social facilitation. She is changing a name she privately likes in order to appeal to other people.
The lost empire. There you go.
