What is the level of measurement In the past 2 weeks how of

What is the level of measurement? -- In the past 2 weeks, how often have you felt stressed, anxious, or worried? (0) Not at all (1) Several Days (2) More than half the days (3) Nearly every day

Solution

This is Nominal variable because there is no (implicit) number attached with the given options (like \"several days\" or \"Nearly every day\"). If convert these options into numerical quantities (0,1,2,3) it will become ordinal variable because it has ordered rankings but difference between 2 ranks is not uniform (or does not make sense)
