Betrouwbaarheid van de First Time Read Yesterday methode

---

Abstract

Up to now in presentations regarding the Yesterday First Time Read-method (YFR), attention has especially been paid to validation of the central reach question. Other fundamental aspects of the method have been pushed into the background. In this article we shall pay attention to one of these items: the statistical margins of the results. The relevance of this subject is evident. For the YFR-method it is particularly important, because in this method the determination of reach is based on a relatively small group of readers, that is, those who read a certain issue yesterday for the first time. Statistical margins can become disproportionately big. In the YFR-method we find - at an equal level of reach - for monthlies less YFR-scores than for weeklies, and for weeklies less YFR-scores than for dailies. So statistical margins for monthlies arc bigger than for weeklies and for weeklies bigger than for dailies.
