An interval scale is similar to an ordinal scale in that the data points are ordered, however in an interval scale, the distances between these points are equal, and run on a linear scale. For instance, the distance between 5 and 10 is the same as the distance between 25 and 30, whether that’s increase in severity of symptoms, how strongly a person exhibits a personality trait, distance, etc.
Statistics, Research Methods, Analysis, Visualisation, Graphs, that kind of stuff.
