Razlika v kakovosti anketnih odgovorov glede na napravo, s katero anketiranec izpolnjuje spletno anketo

Knez, Martina (author), Lozar Manfreda, Katja (mentor)

V zadnjem desetletju beležimo porast spletnih anket in povečano uporabo novih mobilnih naprav. Z naraščajočo uporabo novih mobilnih tehnologij narašča tudi delež anketirancev, ki izpolnjujejo te vprašalnike na pametnih telefonih ali tablicah. Prav zato se vse pogosteje pojavlja tudi vprašanje kakovosti podatkov, pridobljenih na ta način. V magistrskem delu analiziramo podatke, zbrane s spletno anketo med člani spletne skupnosti "Med.over.net". Osredotočimo se na razlike v kakovosti odgovorov glede na napravo, na kateri je bil izpolnjen anketni vprašalnik. Pri tem uporabljamo tako odgovore anketirancev kot tudi parapodatke. Ugotavljamo, da med anketiranci obstajajo razlike glede na uporabljeno napravo na treh od petih opazovanih indikatorjih. Uporabniki pametnih telefonov se od ostalih razlikujejo po spolu in starosti, delež predčasno prekinjenih anket je med njimi višji. Do razlik pride tudi pri deležu neodgovorov, ki je za zaprta vprašanja večji med uporabniki ostalih naprav. Pri vprašanjih odprtega tipa in pri celotnem času izpolnjevanja anketnega vprašalnika nismo ugotovili razlik glede na uporabljeno napravo anketirancev.

• Title: Difference in quality of responses in a web survey when using various devices

Abstract

In the the last decade, we have noticed a significant increase in the use of web surveys, as well as the usage of new mobile devices. With the rapidly growing usage of mobile devices and development of new mobile technologies, the share of respondents who use smart phones or tablet computers for completing online questionnaire, is also rising. Because of that, data quality that is collected with these new devices is put under question. In this thesis we analyze data that was collected using a web survey of members of an online social forum called "Med.over.net". We focus on differences in quality of answers between respondents who completed the questionnaire with different devices. We compare different data quality indicators, using survey answers as well as paradata. We found differences in three out of five data quality indicators. These are: demographic differences, the share of break-off rates and item-non response level. However, there were no significant difference between smartphone and other users as regards open-ended questions and total time for completing the online questionnaire.
