Question

A researcher is trying to understand the impact of the number of children in a household on parental stress. After collecting data, the researcher finds that stress increases when parents move from 0 to 1 child and from 1 to 2 children but plateaus after having 3 or more children. This is an example of a:

a) Positive correlation
b) Negative correlation
c) Nonlinear relationship
d) Causal relationship

Answer 1

The researcher's findings indicate a nonlinear relationship between the number of children in a household and parental stress.

Step-by-step explanation:

The researcher's findings indicate a nonlinear relationship between the number of children in a household and parental stress. The stress increases when parents move from 0 to 1 child and from 1 to 2 children, but plateaus after having 3 or more children. This means that as the number of children increases, the level of parental stress initially rises, but then reaches a point where it no longer continues to increase.
