Answer 1

A person's self-reported life satisfaction on a scale from 1 to 10 is an operational definition for happiness.

Step-by-step explanation:

A person's self-reported life satisfaction on a scale from 1 to 10 is an operational definition for happiness. This definition allows individuals to rate their own level of happiness based on their subjective perception of their overall life satisfaction. It takes into account personal feelings and emotions, making it a valid measure of happiness.
