CATI
CATI (Computer-Assisted TelephoneInterviewing) is a telephone survey conducted by Rating Group's own callcenter. It is about the speed of data collection and a reliable, representative sample.
System and sampling
There are two types of CATI sampling:general representative and targeted.
General representative sample
The general representative sample reflectsthe views of the population of Ukraine, regions, etc. This sample is random andis formed using random digit dialing (RDD). This ensures that citizens in allregions where Ukrainian mobile communications are available at the time of thesurvey have an equal opportunity to participate in the survey. The resultsobtained can be weighted using the latest available demographic statistics forUkraine according to data from the State Statistics Service as of January 1, 2022(https://www.ukrstat.gov.ua/).
Rating Group uses ViciDial software, whichis owned by our company and provides various dialing modes (including IVR) andrandom digit dialing (RDD) calls. The call center achieves random samplingusing software that randomly generates Ukrainian mobile phone numbers based onthe codes of the three largest mobile operators in Ukraine: KYIVSTAR, VODAFONEUkraine, and LIFECELL.
Target sample
Used when you need to find out the views ofa specific category of the population (for example, parents of childrencurrently attending elementary school). Initially, the target sample isconstructed in the same way as a general representative sample. However, whencalling a random number, screening takes place: the operator asks therespondent several filter questions. If the respondent meets the criteria ofthe target group, he/she is included in the target sample (the surveycontinues). If the respondent does not meet the criteria, then he/she is notincluded in the sample (the conversation ends).
Quality assurance
Rating Group conducts logical checks of thedata set and monitors audio interviews both online and in recordings. We havedeveloped a comprehensive system for monitoring and improving the effectivenessof our interviewers. It includes regular assessments using quality charts andtraining to improve their skills and qualifications. In particular, thefollowing measures are provided for:
Corrective measures are applied based onthe evaluation results. If critical errors are detected, this leads to theexclusion of the interview from the data set and additional training andtesting for the operator. In addition, at least 10% of completed questionnairesare checked by controllers by listening to the audio recording.
To validate the data, Rating Group usesprocedures to control the quality of respondents' answers using correlationanalysis. The first procedure involves constructing a “response quality” scale,which monitors the time taken by the respondent to complete the questionnaireand the variability of their responses in order to avoid skimming through thequestionnaire and adding a question to the questionnaire to test attentiveness.The second procedure involves checking for statistically significant correlationsbetween data from different survey waves.
