Comments
Internet usage by intensity and by location are close to 10%, the concerns on information security matters are located around 20%, the middle values of e-mail and experience of Internet users are approaching 30%;
Data spread (IQR) is largest in the e-mail usage and security concerns in online shopping, the smallest - in the Internet usage over 6 hrs/week intensity;
Mobile technologies have a wide spread of data and are visibly different;
Almost all indicators show departures from symmetry in data distributions;
Lithuania’s results in many indicators is near the first quartile Q1 – fairly good results, while Austria – nearly Q3, shows much better results.

Comments
There is no discernible difference between V4 and Baltic countries groups in the considered indicators from the Basic access and usage/Information security areas;
CZ is a leading country among the V4 countries (except concerns on security matters);
LT and LV performed rather similarly in all considered indicators while EE has visibly outstanding results

Measuring NAS Achievements in the EU15 Context (1)
Let Δ1, …, Δ k – are the values derived for each indicator (in the considered area)
λ – the threshold value The DECISION RULE on the i-th indicator
contribution in the area: if Δi< λ, the contribution is not significant, if Δi > λ, the contribution is significant;
Let r values among k were significant, introduce
MARK = 1 – r/k
Measuring NAS Achievements in the EU15 Context (2)
Evidently 0 < MARK < 1 Small MARK values mean small NAS
achievements compared to EU15 If the value is approaching 1 – the NAS
and EU15 achievements are comparable If the value is close to 0.5 – a middle NAS
success discovered in that area.
Each SIBIS area such as Basic Access, eWork, Digital Literacy and others
acquire own MARK value.

Conclusions
Box Plot was applied to SIBIS data in order to see a position of any separate country in the context of enlarged EU and to see how the inclusion of 10 new NAS countries do affect the common results
The measure MARK expressing EU-NAS differences numerically have been developed and applied to get a clear picture of eEurope-plus at a glance
Notice, that in principle the results derived here have an “optimistic” trend, because the data of EU – GPS 2002 survey has to be compared with the NAS – GPS 2003.
