TYPES OF WEB SURVEYS
o Non-probability Approaches
o Probability Based Methods
PROBABILITY BASED METHODSo Intercept Surveyso List-based samples of high-
coverage populationso Mixed-mode designs with
choice of completion methodo Pre-recruited panels of
internet userso Probability samples of full
population
INTERCEPT SURVEYS
PROBABILITY BASED METHODSo Intercept Surveyso List-based samples of high-
coverage populationso Mixed-mode designs with
choice of completion methodo Pre-recruited panels of
internet userso Probability samples of full
population
LIST-BASED SAMPLES OF HIGH-COVERAGE POPULATIONS
PROBABILITY BASED METHODSo Intercept Surveyso List-based samples of high-
coverage populationso Mixed-mode designs with
choice of completion methodo Pre-recruited panels of
internet userso Probability samples of full
population
MIXED-MODE DESIGNS WITH CHOICE OF COMPLETION METHODResearchers can combine several above
methods for the data collection. o Computer-assisted personal
interviewing (CAPI).o Audio computer-assisted self-
interviewing (audio CASI).o Computer-assisted telephone
interviewing (CATI)o Interactive voice response (IVR).o Web surveys
PROBABILITY BASED METHODSo Intercept Surveyso List-based samples of high-

MIXED-MODE DESIGNS WITH CHOICE OF COMPLETION METHODA probability sampling method is any
method of sampling that utilizes some form of random selection.
SURVEY QUALITY
o Coverage and sampling error
o Non-response erroro Measurement error
ONLINE SURVEY PROSo Easy access to respondentso Low cost compared to other
methodso Large-scale data collection is
possibleo Multimedia content can be usedo Anyone with internet access can be
targeted
EASY ACCESS TO RESPONDENTS
