Interval or ratio? quantitative interval level (a.k.a differences or subtraction level) may initially look like a qualitative ordinal variable (e.g. low, med, high), but levels are quantitative in nature and the differences in levels have consistent meaning. scale for evaluation:.

Variables and hypotheses an important part of scientific research is forming a hypothesis—a testable statement about the relationship between two or more variables. a variable is a logical grouping of attributes that can be observed and measured and is expected to vary from person to person in a population. in social science research, variables have two important properties—they are.

Variables are used to measure concepts that cannot directly be measured, like satisfaction, by identifying indicators. variables are also classified by their role in relationships between factors, by how they are measured in studies, and by the scale of their units of measurement, like nominal, ordinal, interval, and ratio scales. Levels of measurement and choosing the correct statistical test most textbooks distinguish among nominal, ordinal, interval, and ratio scales based on a classification system developed by stevens (1946). choice of the statistical analyses in the social sciences typically rests on a more general or cruder classification of measures into what i will call “continuous” and “discrete.
