Numeric Attribute Types Quantity(integer or real-valued) Interval Measured on a scale of equal-sized units Values have order E.g temperature in C or F calendar dates No true zero-point Ratio Inherent zero-point We can speak of values as being an order of magnitude larger than the unit of measurement (10K° is twice as high as5K°) e.g. temperature in Ke/vin, length, counts, monetary quantities7 Numeric Attribute Types ◼ Quantity (integer or real-valued) ◼ Interval ◼ Measured on a scale of equal-sized units ◼ Values have order ◼ E.g., temperature in C˚or F˚, calendar dates ◼ No true zero-point ◼ Ratio ◼ Inherent zero-point ◼ We can speak of values as being an order of magnitude larger than the unit of measurement (10 K˚ is twice as high as 5 K˚). ◼ e.g., temperature in Kelvin, length, counts, monetary quantities
