Zewde is usually very friendly and outgoing. She is typically polite to others and always leaves a large tip when she goes out to eat. Earlier today, however, you saw her yell at a waiter at a local restaurant. You also noticed that other customers yelled at this waiter. According to Kelly's attribution theory, you are likely to make a(n) ______________ attribution for Zewde's behavior.

Harold Kelly proposed the covariation model. This model talks about attribution theory that deals with how individuals and others behave in a given way.

The attribution theory is based on 3 parameters namely:

1. Consensus

2. Consistency

3. Distinctiveness

A behavior is said to be external when the subject individual has no control over it due to the other party involved behaving in a certain way to the subject.

It is internal when the subject individual has control over their behavior.

In this case everyone knows Zewde as a nice individual who gives large tips when she goes out to eat so when she and other customers yell at the waiter then it means the behavior is certainly from the waiter. She has no control over the behavior which makes it an external attribute.
