STATISTICAL ANALYSIS OF HOSPITALITY SERVICES IN ROMANIA USING THE RANK-ORDERING METHOD.

Summary/Abstract: This paper is based on research performed in 2010 at the guesthouse "Casa Ecologica” for hospitality services. The paper wants to verify the results previously obtained using other statistical methods. Also, we want to verify the feedback concerning the improvement of the hospitality services, as we have recommended. We have used the Laplace function (the z test) to compare the average grades of the two samples (the first sample represents the respondents of the first period and the second consisting of respondents of the second period, for the same questionnaire) for each service of hospitality separately, and their confidence intervals. Also, we used the rank-ordering method for research the customer preferences regarding to the hospitality services. The results for the guesthouse “Casa Ecologica” will be compared with those previously obtained at national level.
