Assign points for various responses (weighted analysis to achieve 100% on scale/index).
Are we looking at a score or a frequency?

“Ladder question”

01 — R — C — M — 25
02 — D — L — M — 38
03 — SD — L — F — 27
04 — D — L — M — 20

“Code” is used for individual responses instead of names; maintain integrity of sample

Unit of analyis: the person/place/thing from which we take measurements (the subject of study)
