A researcher investigated whether an environmental nudge could encourage commuters to use the stairs instead of the escalator at a busy subway station. The researcher painted interactive 'piano keys' on the stairs to make climbing them more appealing.

During a peak morning commute from 7:30 am to 9:30 am, the researcher observed and recorded the choices made by commuters, categorizing them based on whether they carried heavy luggage and which path they chose.

Table 1: Number of commuters choosing the stairs or escalator, categorized by luggage status

	Commuters with luggage	Commuters without luggage
Stairs (piano keys nudge)	12	54
Escalator (no nudge)	42	28

Outline one strength of the use of the nominal data collected in this study.
