Table 1.
Distribution of the PIAAC sample with respect to the three subsamples analyzed in the study (4, 5, 6), people without a score in PS-TRE, and other people not analyzed in this study. Total numbers, percentages of the whole population, values for literacy (LIT, means, (standard deviations), and (competency levels)), and values for numeracy (NUM, means, (standard deviations), and (competency levels)).
| N | Percentc | LITb | NUMb | |
|---|---|---|---|---|
| (1) No computer experience | 360 | 6.6 % | 227.81 (47.47) (II of V) | 213.54 (55.12) (I of V) |
| (2) Basic computer test failure | 178 | 3.3 % | 246.33 (51.12) (II of V) | 224.94 (53.93) (I of V) |
| (3) Computer-based assessment refused | 297 | 5.4% | 255.97 (45.61) (II of V) | 245.44 (50.02) (II of V) |
| (4) Employed – computer use at work and at home | 2741 | 50.2 % | 285.86 (41.09) (III of V) | 293.01 (43.85) (III of V) |
| (5) Employed – computer use only at home | 659 | 12.1 % | 257.24 (43.02) (II of V) | 263.88 (43.93) (II of V) |
| (6) Out of the labor force | 707 | 12.9 % | 267.80 (46.42) (II of V) | 267.16 (48.38) (II of V) |
| (7) Othera | 523 | 9.6 % | 259.02 (46.92) (II of V) | 262.54 (47.81) (II of V) |
| (8) Total | 5465 | 100.0 % | 269.92 (47.35) (II of V) | 271.87 (52.93) (II of V) |
This category comprises several fragmented sub-groups, e.g. unemployed people, people using their computers only at work etc., each of them consisting of less than 130 people.
Competency levels: I: 176–225 points; II: 226–275 points; III: 276–325 points; IV: 326–375 points; V: above 376 points.
Deviations to the percentages reported by Zabal et al. (2013) have their origin in a differing filtering focusing on the three sub-samples of the study and excluding cases with missing variables.
