Figure 1. Mean scores for vaping clusters in a four-cluster solution.

Table 1. The four-cluster solution with the main effect and mean scores for each cluster by variable.

	Variables
Four-cluster solution	Days vaped per week	Vaping episodes per day	Puffs per episode
Main effect	F
	88.52*	15,388.99*	21.52*
	Mean score by cluster variable
Daily heavy and binge vapers (n = 187)	7	99.57	8.74
Daily heavy vapers (n = 206)	7	51.68	5.69
Daily moderate vapers (n = 381)	7	21.86	5.69
Non-daily light vapers (n = 554)	5	6.50	5.72

Note: Main effect (F) is derived from an analysis of variance. *p < .001.

Notes: Pearson chi-square was used for all crosstabulation analyses. *p < .05. Column percentages are included for variables that significantly varied by cluster membership. Each roman superscript (i) and (ii) denotes a subset of the variable that significantly differs by cluster membership. Categories with different roman superscripts denote column proportions that differ from each other at p < .05.
