Annual Income as an Attribute, Discrete or Continuous Variable
Annual income is a measure of how much money an individual earns in a year. It is an important variable in many fields such as economics, finance, and sociology. The following sections will explain whether annual income is an attribute, discrete or continuous variable.
Annual Income as an Attribute
An attribute is a characteristic or property of an object, person, or phenomenon. Annual income can be considered an attribute because it is a quality or feature of an individual that can be used to describe them. It is a piece of information that can be used to help identify and classify people based on their level of income.
Annual Income as a Discrete Variable
A discrete variable is a variable that can only take on whole numbers or specific values. Annual income can be considered a discrete variable if it is measured in increments such as $1,000 or $10,000. For example, if someone earns $50,000 per year, it is not possible for them to earn $50,001 per year. In this case, annual income would be considered a discrete variable.
Annual Income as a Continuous Variable
A continuous variable is a variable that can take on any value within a range. Annual income can be considered a continuous variable if it is measured as a range of values (e.g. $40,000 to $50,000). In this case, someone who earns $45,000 per year falls within the range of values and annual income would be considered a continuous variable.
Conclusion
Whether annual income is considered an attribute, discrete or continuous variable depends on how it is being measured. If it is being measured in specific increments, it is a discrete variable. If it is being measured as a range of values, it is a continuous variable. And if it is being used to describe an individual, it is an attribute. Therefore, the answer to the question is (d) either (b) or (c).
