Decision making by managers that is based on inefficient and ineffective marketing research may do harm putting a firm at risk. The minimization of such a risk is possible when an appropriate selection of analytical models is conducted, allowing a firm to measure the level and structure of efficiency related to marketing research expenditures and the real effects (economic results). In the first part of the article the author describes the essence and main problems associated with marketing research efficiency analysis. In the next part, a generalized model of marketing research efficiency is proposed with s discussion throwing light upon two important models: SEM (Structural Equations Model) and MRA (Multivariate Regression Analysis).

Factors Analysis is often tied to specific properties of population and its culture characteristics. If measurement is applied from population to another, then extracted factors may hard to be equally compared on the reflective basic level, unless all conditions of invariance measurement are met. Hence, implementation of customers research and any inter-cultural studies require a multi-cultural model describing statistical differences in both cultures with invariance as underlying assumption. In the article we implement a model for analysis of customers’ personal values pertaining to hedonic consumption aspects in two culturally opposite populations. We conducted survey in two countries and the following cities: Poland (Poznan) and The Netherlands (Rotterdam and Tilburg) with randomly prepared samples with youth representatives on both sides. This model permitted us for testing invariance measurement under cross-group constraints and thus examining structural equivalence of latent variables - values.

In the literature factor analysis is admittedly a well-known and effective multivariate method in the reduction of extensive and broad data, e.g., in the analysis of too many variables. It is also known for the process of unidimensional or multidimensional scale/s construction. Typically, in many studies (especially those pertaining to market research area) a common factor analysis solution is used (based on continuous data). However, there are rarely ever undertaken studies pertaining to latent variable models where other type of data is used based on discrete variables. One of these models might be called Latent Profile Factor Analysis - LPFA. In this article author’s main objective is to propose and discuss its (LPFA) main assumptions. In order to prove the model’s functionality in practice of market research, a brief example of LPFA model for ordered categorical data (based on one-factorial solution) in reference to hedonic consumption data is given at the end of the paper.

W artykule rozważane są wzajemne powiązania badań ilościowych i jakościowych. W pierwszej kolejności zdefiniowano istotę i założenia tych badań oraz dokonano porównań pomiędzy nimi w oparciu o zasady filozofii, kwalimetrii (działu nauki zajmującego się teorią jakości) oraz statystyki. Następnie omówiono różnice występujące pomiędzy obydwoma rodzajami badań w kontekście planowanych zadań badawczych. W dalszej części opracowania opisano możliwości skutecznego łączenia badań ilościowych i jakościowych w procesie triangulacji.

This article examines the interrelationships between quantitative and qualitative research. Firstly, the essence and assumptions of quantitative and qualitative research methods were defined and the comparison between them was made on the basis of philosophy, quality metrology (a branch of science dealing with quality theory) and statistics. Moreover, the differences between the two types of research were discussed in the context of the planned experiments and empirical research. In the next part of the study, the possibilities of effective integration of quantitative and qualitative research in the process of triangulation were described.

The article discusses issues concerning the scale design based on one-parametric Rasch model in the context of consumers’ attitudes. The first part describes the specificity of the measurement in the light of Item Response Theory (IRT). In particular the attention is paid to the nature of the dichotomous data used in the model. At last, the author presents the scale in reference to attitudes of people towards their hedonistic, consumer lifestyle.

W artykule autor omawia zagadnienia dotyczące konstrukcji skali pomiarowej postaw konsumenckich w kontekście jednoparametrycznego modelu Rascha. W pierwszej części opisano specyfikę pomiaru w świetle teorii reakcji na odpowiedzi (IRT) oraz założenia teoretyczne stanowiące podbudowę konstrukcji skal pomiarowych. Szczególną uwagę zwrócono na charakter danych dychotomicznych. W końcowej części opracowania zaprezentowano problem badawczy w sferze konstrukcji skali do analizy postaw konsumentów wobec konsumpcyjno-hedonistycznego stylu życia. W pomiarze wykorzystano jednoparametryczny model Rascha.

Since its beginning, the European Union has transformed, undergoing many stages of integration, from its origins as a free trade zone, to a customs union, on to a common market, then to an economic monetary union. The establishment of the euro zone was an economic plan aiming to increase the competitiveness of the European economy. At present this economic plan is being embraced by the Polish economy. In this context, the prospect of our country, joining the monetary union, from the perspective of Polish companies, is of particular importance. The main aim of this paper is to attempt to recognize whether Poland’s access to the euro zone is perceived as an opportunity or a threat by Polish managers. First, the authors, by quoting literature written on the subject will present the opportunities and threats related to the functioning of the economic monetary union, then illustrate how they pertain to Poland. This overview is accompanied by empirical research, which took a form of direct interviews conducted in 230 companies from all over Poland.
