Nominal vs ordinal • Attribute “age” nominal • Attribute “age” ordinal (e g “young” < “pre-presbyopic” < “presbyopic”) If age = young and astigmatic = no and tear production rate = normal then recommendation = soft If age = pre-presbyopic and astigmatic = no and tear production rate = normal then recommendation = soft
Scales of Variable Measurement Nominal Ordinal
ordinal interval or ratio scale variables Ordinal Ordinal scales build upon nominal scales by assigning numbers to objects to reflect a rank ordering on an attribute in question For example assigning ID codes 1 2 and 3 to represent a persons response to a question regarding use rate: 1 = use often; 2 = use sometimes; 3 = never use
