Table 3.

Distribution of participants to one of the two clusters, as a function of their self-described gamer identity.

Gamer Identity	Cluster 1: tolerate	Cluster 2: troubled	χ 2	p
Casual gamers	61	62	0.01	0.93
Competitive gamers	142	183	5.17	.02*
Amateur athletes	18	56	19.51	.00000999***
Part-time professionals	6	20	7.54	.006**
Full-time professionals	1	11	8.33	.001**
Speedrunners	4	4	0	1

All distributions were tested against equal distributions using the χ² statistic. A significant χ² test implies an unequal distribution of people between the two clusters for any given self-identified gamer type. For example, casual gamers are split 50/50 between the two clusters and thus the χ² test is non-significant. However, full-time professionals overwhelmingly fall into the second cluster and thus the χ² test is statistically significant. Note that the test outcome can be interpreted with more confidence if the underlying sample is larger.
