Note: the differences among the clusters in categorical variables (including system data) were tested using chi-square, in scale variables, using one-way ANOVA with Tukey post hoc tests. Clusters: (1) computer owners who do not use computers personally, (2) IT technicians, (3) owners sharing the computer, and (4) sole users and seldom owners.
