An individual federal tax return form asks, among other things, for the following information: income (in dollars and cents), number of dependents, whether filing singly or jointly with a spouse, whether or not deductions are itemized, amount paid in local taxes. Describe the scale of measurement of each variable, and state whether the variable is qualitative or quantitative.

Could you be so nice and help me check my answers, thank you sooo much

income (in dollars and cents)
quantitative / ratio

number of dependents
quantitative / ratio

whether filing singly or jointly with a spouse
qualitative /nominal

whether or not deductions are itemized
quantitative / ratio

amount paid in local taxes.
quantitative / ratio

Thank you so much, it is so important to me . I'm really appreciate your help, thank you:))

Your answers are almost correct, but there is one error.

income (in dollars and cents):
You correctly identified this as a quantitative variable. However, the scale of measurement for income would be considered an interval scale, not a ratio scale. This is because the zero point on the scale (i.e., $0) does not represent the absence of income. It is just an arbitrary point on the scale.

number of dependents:
You correctly identified this as a quantitative variable. As the number of dependents can be counted and ranked, it is considered a ratio scale.

whether filing singly or jointly with a spouse:
You correctly identified this variable as qualitative, specifically nominal. This means that the responses do not have an inherent order or numerical value associated with them.

whether or not deductions are itemized:
This variable should be considered qualitative or categorical, rather than quantitative. The responses are "yes" or "no" options, which do not have numerical value or order.

amount paid in local taxes:
You correctly identified this as a quantitative variable. It is a ratio scale because it represents a measurable quantity and has a meaningful zero point (i.e., paying $0 in taxes means no taxes were paid).

Overall, your understanding is good. Just remember that nominal and categorical variables are qualitative, while quantitative variables have numerical value and can be measured or counted. Well done!
