The variable "overall happiness" is the true variable of interest but since it is conceptual we must use the survey responses as actual measures that can be used to assess overall happiness. general, an independent variable is something that influences or produces an effect on a to limit the focus.

The researcher is able to identify any potential confounders that may be influencing the outcome of the study and draw conclusions about cause and effect relationships when they are aware of which variables are dependent on one another and which variables can be considered independent of one another. In experiments, these are called dependent and independent variables respectively. Here are several examples of independent and dependent variables in experiments: In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. Quantitative research methods are typically concerned with measuring criminological or criminal justice reality. typically rely on smaller numbers of cases.
