The research was ... order for psychologists to study automatized behaviours they tend to put participants in situations where an automatized behaviour is in conflict with a desired one. This allows them to study and test particular characteristics of automatized behaviours by noting their influence on other easily measured behaviours. Experiments similarly categorised or related to ...

This analysis reveals that the distribution is significantly different from the normal distribution, according to Kolmogorov-Smirnoff's test (z = 3.49, p _ 0.001). More specifically, the distribution is skewed in the sense that the majority of the customers are satisfied rather than dissatisfied.
