Good morning I want to double check my thoughts on some practice variables measurements. Please review below and deicide if each variable is ordinal or scale and why. Please know for this class.....SCALE....is consider INTERVAL & RATIO data.....so both are just considered scale measurement.

	ordinal or scale? why?
Events	number of stressful life events that had occurred in the last year
Error1	this number represents identification of OSHA hazards before completing the annual OSHA training (higher # = identification of more errors)
Error2	this number represents identification of OSHA hazards after completing the annual OSHA training (higher # = identification of more errors)
Skills1	skills assessment taken within the first week on the job (higher = better skills)
Skills2	skills assessment completed after 6 months on the job (higher = better skills)
Skills3	skills assessment completed after 1 year of service (higher = better skills)
Salary1	salary at time of hire
Salary2	current salary
Years	number of years employed
