This is the most frequent method of data collection applied in Kosova. Although most countries rarely use now face-to-face interviews since it costs more, it is time-consuming and requires more training for interviewers and supervisors, this is the most appropriate method for circumstances in Kosova, because of the low penetration of fixed telephony and the Internet. To ensure a representative sample, multi-staged stratified sampling is applied.
Because of the low penetration of fixed telephony in Kosova (35% of households), telephone surveys are rarely used. Therefore, information gathered from telephone surveys in Kosova can never be nationally representative. Only in cases when specific target is required or when we need approximate information, telephone survey is used.
Intercepts are usually used when a particular target group is sought or when audio and video view is required. Usually it is used in places where a specific target group tends to frequent, such as shopping malls, specific bars and cafeteria, etc.
Diary panels are most useful in media and market research – better say when measuring consumer habits and behaviours. They are usually longitudinal studies in which cases the diaries are left to participants for self completion for a period of time. Then after a specific period, the same respondents complete the same diaries which enable us to compare the data regarding respondents’ behaviours and consumer habits within a specific time frame
