Abstract: | AbstractConclusions of sample surveys dealing with matters of privacy are often disputed. Many people either refuse to participate or provide false answers. Indirect questioning techniques are designed so that reliable estimates can be produced while the privacy of the participants is protected. One such method, the Item Count Technique is gaining increasing popularity. However, the original version of the method does not fully protect the privacy of the participants. In this paper we propose a new version of the technique which better protects the privacy of the respondents and does not have the so-called floor and ceiling effects. |
