Answer 1

Correlation is a study of relations between two variables. If A happens then there is a chance that B will also follow. The correlation can be positive or negative if variable A increases than the variable B will also increase, and in negative correlation theory if variable A increases then variable B will decrease. The simple example of a jingle (variable A ) of an ice cream truck and the distance of the truck (variable B), If ice cream truck is nearby louder the jingle, means variable A increases closer the variable B.

Normative is establishing or deriving from a standard or norms especially of behavior. Normative history-graded influences are those influences within the life course that is correlated with the historical time and are experienced by the majority of people or by generation. This involves a change in behavior, and this gives evidence that human is social in need companionship and association.
