Explanation:

• Nominal data is categorical without order. Ratio has a true zero point. Ordinal has an order but non - equal intervals. Interval has equal intervals but no true zero.
• For "Change in health (scale of - 5 to 5)", there are equal intervals between values (-5, -4, -3, etc.) and no true zero (a value of 0 doesn't mean absence of health change), so it is interval data.
