Explanation / Answer
Gender - Nominal ; Nominal Variable is the one that has two or more categories but there is no intrinsic ordering to the categories; The possible categories are Male and Female and there is no intrinsic order for them.
mg of morphine : Continuous Variable If a variable can take on any value between its minimum value and its maximum value, it is called acontinuous variable
Age - Continuous - Although the recorded ageshave been truncated to whole numbers, the concept of age is continuous
Number of cigarettes per day (possible responses = 0, 1-3, 4-7, 8-10, 11-20, 21 or more) - Ordinal
An ordinal variable is similar to a categorical variable. The difference between the two is that there is a clear ordering of the variables.
Osteoporosis diagnosis (yes/no) - Nominal ; Nominal Variable is the one that has two or more categories but there is no intrinsic ordering to the categories; The possible categories are Yes and No and there is no intrinsic order for them.
Servings of fruit/vegetables per day (possible responses = 0-3, 4-7, 8-11, 12-15, 16-19, 20-23, 24-27) - Ordinal
Respondents perceived health (Very Poor --> Excellent) - Ordinal
