Nowadays, lots of people are collecting data using online surveys. How do you rate online surveys? What are pros and cons of it? Any authentic reference for this?
Someone will answer, Online survey is better while other will favor self-reported approach. Those will favor online survey if they can't access respondent physically. If they have large number of respondents, if they have online based study, have main objective to conduct online survey etc. (depends on researchers objectives).
Self-reported survey has own significance, for instance, it has higher response rate than online survey. In addition, little missing values chances (*), easy if small population and have access to respondents. Respondents feel friendly to answer question unlike in online survey where respondents fill questions without focusing.
I recall again that it dependents on research objectives/researcher choice. It is elusive to proc and cons in this way bcs To me self-reported will better while you may prefer online survey. No one is fully support one option.
You will get answer of this question if you conduct both survey in one study. Probably, you will prefer self-reported (Hard copy) approach or will be the fortunate if favored online survey.
Every method for data collections has advantages and disadvantages. Online data collection can reach any distance on earth with almost no cost. The control over the sample is weak, the response rate is low, having access to data skills of filling questionnaires could be another limitation.
Lower cost to administer the survey - because merely via online Internet vs hardcopy survey questionnaire printing costs, postal charges, return stamped enveloped included in mailing envelopes etc.
Faster for respondents to complete the online survey & respondents can fill up anytime 24 x 7 and suitable for respondents in different time zones.
Lower probability of incomplete survey / missing data i.e. respondents didn't fill up certain questions - because online survey can be configured so that all questions have to be completed before respondents can click "submit" button (note: some researchers might not agreed this as advantage because they believe respondents should have the right not to fill up certain question(s) if they don't understand / simply they don't want to i.e. based on voluntary basis).
Lower effort to convert from online data (records in database or Excel etc.) into statistical software for subsequent data analyses - vs hardcopy questionnaire data that need to be entered manually into statistical software.
Disadvantages of Online Survey:
No researcher / research assistant onsite to administer / clarify questions from respondents when they don't understand certain questionnaire questions or need clarifications.
Inferior data quality sometimes collected - since no researcher onsite to supervise the respondents as per hardcopy survey, some respondents might just simply fill up the online survey without reading each question carefully.
Data only collected from respondents that adept to ICT or have gained access to Internet whereby no Internet access / non-ICT respondents are left out.
