A researcher seeks to investigate whether an individual’s life satisfaction (happiness) is associated with gender and working status.
The variable Gender includes two categories: Male and Female, while Working_Status comprises three categories: Self-employed,
Student and Job. A random sample of ten participants was selected from each category. Life satisfaction was measured on a scale ranging from 0 to 100, with higher scores indicating greater happiness.
Therefore, the dependent variable is life satisfaction (happiness), and the independent variables are gender and working status.
