Using Partial Correlation Coefficient to Assess the Importance of Quality Attributes: Study Case for Tourism Romanian Consumers

Olimpia-Iuliana Ban and Victoria Bogdan
Abstract—The importance-performance grid is a marketing instrument used to optimize the attributes of products in order to increase the consumers’ satisfaction. A special place for debates is represented by the way in which the importance of attributes is determined, the direct research way having many weak points, among which we mention: it aggravates the application of the survey, the answers are already influenced by the perceived performance of the products, the answers are not authentic or they are too polite so that the values obtained are high and the inter-item differences are little and pointless etc. The aim of this paper is to test a mathematic method recommended by the literature in the field, in order to indirectly determine the importance of the attributes, starting from the evaluation of the performance of products in relation to global satisfaction. Methodology contain: a survey through a questionnaire which recorded the importance assigned by candidates to the quality attributes and evaluated the performance of the touristic services considering the quality attributes; determined the importance of the attributes through the partial correlation coefficient, by correlating the attributes’ perceived individual performance with the global satisfaction and compared the two matrixes pertaining to the information obtained by the two ways considering the marketing decisions. The results obtained indirectly through the partial correlation coefficient substantially differs from the results obtained by directly investigating the importance of the attributes, in order to make marketing decisions. The present paper continues previous researches, in which we tested two methods meant to indirectly determine the importance of the attributes, the Spearman coefficient and the entropy calculus.
