Methodology and Analysis
The sample population was drawn from the main user of the 43.9
million mobile-cellular subscriptions in 2016 with Mobile Station
International Subscriber Directory Number (MSISDN) identical to randomly
generated numbers.
The survey adopted confidence level of 95% and precision of ±2%
for Internet users while ±3% for non-users. There was only one stage of
sample selection as the survey adopted a simple random sample (SRS)
approach. Sampling was done across mobile networks with probability
proportional to size of the networks in terms of subscriptions.
The survey was canvassed and administrated using a Computer
Assisted Telephone Interview system operating out of MCMC CATI Centre
in Cyberjaya. Fieldwork for this survey started on 14 November 2016 and
ended on 10 February 2017. The survey reached to a sample of 2,402
Internet users and 1,067 non-users.
Data quality check was administered throughout the survey fieldwork
and upon its completion. Next, basic frequency count was computed to
assess the results pattern. Cross-tabulation was imposed between relevant
indicators to identify significant relationships that would deduce meaningful
inferences pertinent to the objectives.

Malaysian) and ethnicity distribution, where the current population
estimates from Department of Statistics Malaysia (DOSM) serves as the
auxiliary information as follows:
