E-COMMERCE CONSUMERS SURVEY 2018
SECTION 3: METHODOLOGY
METHODOLOGY AND ANALYSIS
The sample population was drawn from users of mobile-cellular with Mobile Station
International Subscriber Directory Number (MSISDN) identical to randomly
generated numbers. They are the main users of mobile-cellular number.
ECS 2018 was canvassed and administered using a Computer Assisted Telephone
Interview (CATI) system operating out of MCMC CATI Centre in Cyberjaya. Fieldwork
for this survey started on 28 August 2018 and ended on 27 November 2018. The
survey adopted confidence level of 95% and precision of ±2% for national level, and
reached to a sample of 2,401 e-Commerce consumers. As for the state level,
confidence level was at 95% and ±7% precision to reach 200 respondents for each
state.
There was only one stage of sample selection as the survey adopted a simple
random sample (SRS). Sampling was done with probability proportional to prefix in
terms of subscriptions for mobile-cellular.
Data quality check was administered throughout the survey fieldwork. 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 objective of the survey.
Important findings are featured in the form of a report, complemented with
supporting charts and tables for the convenience of readers. Findings on current
trends were analysed against evolutions that took place around the world.
Information from external sources are included as supplementary data to support
any findings. The definitions of terminologies adopted in this survey were referenced
to the international standards and existing frameworks.
