In this paper the author introduces alternative sampling designs based on order statistics, i.e. ranked set sampling RSS and extreme ranked set sampling ERSS. It is known that RSS is in many cases more efficient than the widely used standard simple random sampling SRS, i.e. it gives more precise assessments of basic population parameters. And what is important, the increase of the efficiency can be often achieved at no additional cost or very little cost. The major objective of this paper is to present a possibility of application of the RSS procedure in market and consumer surveys. The author introduces and analyses an example of sales estimation in pharmacies. The method of data collection in this survey is exact (without non-sampling errors) and is done by a connection with pharmacies' computers. An additional information used in the survey is qualitative data from questionnaires, which are known to be not exact because of non-sampling errors (e.g. intentional incorrect answers, poor memory etc.). In the presented survey errors affect about 50% of the questionnaires. Despite of these errors, the use of auxiliary information in the form of qualitative data leads to the increase of the efficiency of the estimation and gives more precise assessments than the widely used simple random sampling. The problem is analyzed on a basis of a simulation study. Also another example of a successful application of RSS method is presented. The author analyzes a survey, which is aimed at estimation of the number of pharmacies in Polish towns of 10000-100000 inhabitants. A concomitant (auxiliary) variable used to implement the ranking is the number of inhabitants in the town. In a conducted simulation study RSS also proved to be superior to standard simple random sampling and gave much more precise assessments. (original abstract)
