Document Summary
Objectives: understand how to move from variables to indicators, levels of measure. If you are doing a survey or interview for a project you will state that your indicator is question 6 how do you feel about the current gun control legislation to represent the variable support for gun control legislation. Level of measurement: note: depending on the text/prof. /boss these definitions can fluctuate a bit! I will explain in class: nominal - one category is neither higher nor lower than any other category - they are simply different categories. Interval/ratio - the zero point is aligned with true zero - zero income means you have no income. The gaps between categories are equal -the gap is ,000 between ,000 and ,000 as it is between ,000 and. Interval: raw income scores - sh - ,000. Raw age score - 18 - 80 years old.
