I need a graphical presentation or simple conceptual presentation of the type of varaible and measurement scale in a comprehensive manner.
I could understand clearly all the terms like qualitative variable, quantitative variable; nominal, ordinal, ratio and interval scale.
But, I need a clear and comprehensive classification of the variable and measurement scale
For quantitative variables, the scale of measurement will depend on the units you are using, por example, mm, can be from 0-99 mm, higher values will need cm, and so on.
For qualitative variable you should define your scale, for instance, if you are measuring the level of satisfaction over something, you can use a likert scale using values from 0 to 5 or depending on your degrees of satisfaction: 0-for nothing, 5 for complety satisfied.
