    Opis:
    The aim of this article is to present the possibilities of using correspondence analysis in the study of changes in the gymnasium exam results in Poland. The study used exam results from 2003 and 2010 of the Regional Examination Board, which consist of two regions: Lower Silesia and Opolskie. The usefulness of correspondence analysis using multiway contingency tables and correspondence analysis of supplementary points is shown. From the examinations’ differences between the levels of exam results in both years, gender and place of exam are indicated.

    Opis:
    In this paper an investigation of social media marketing techniques of Coworking spaces’ type of business is performed, using datasets acquired using social media monitoring tools. Mediatoolkit has been used to scrap data deriving from the activity of the WeWork Instagram and Twitter accounts which were collected on a 24/7 basis from varying locations and in multiple languages in a fifteen-day time window. Indices related to sentiment, reach, influence, number of followers, retweets, likes, comments, and view scores formed the datasets that were examined by applying multiple correspondence analysis as well as the hierarchical clustering method. The aim of this paper was to explore the inherent properties of the multiple indices describing the general realm of social media marketing tools, and more specifically aspires to provide digital marketers with an alternative perspective of social media marketing strategies related to the emerging coworking spaces type of business. The authors identified three classes/segments of posts, whereas post polarity tends to relate to geographic location, regardless of the social media channel used for posting.

    younger and older generation
    Opis:
    The paper attempts to verify the hypothesis of the existence of generational differences in the perception of the conditions and quality of work. The research issues considered in this paper are chosen following the regularities observed in the labor markets indicating that special attention should be paid to two age groups: the youngest and the oldest persons. The highest unemployment rate in the EU is observed among young people who encounter various barriers at the beginning of their professional career. On the other hand, the older group of people is expected to provide an important contribution to the labor force to face the problem of aging societies. The objective labor market indicators should be confronted with the results of the subjective opinions of the labor market participants in order to have a comprehensive outlook of the situation. The chosen multivariate method is applied to analyze the opinions of both young and older Europeans taking into consideration the spatial diversity. The opinions about current work given by European Social Survey respondents are analyzed, among others these are the variety of current work, possibilities of learning new things at work, effort-salary relation, support received from other workers etc. The paper presents some results obtained from the applications of correspondence analysis whose usefulness is determined by the measurement scales of the regarded variables.

    Opis:
    The deterioration of the general investment climate, the economic recession, and changes in consumption patterns caused by the COVID-19 pandemic have forced various foreign investors to restrict or suspend investments. One of the possible reactions by investors to the coronavirus crisis is divestment. This article aimed at detecting and analysing the regularities between the risk of foreign divestment in various industry branches and the destinations of FDIs at the level of NUTS 1 macroregions of the Visegrad Group countries during the COVID-19 pandemic, using correspondence analysis. The results of the assessment of the risk of foreign divestment in NUTS 1 macroregions of the Visegrad Group countries are characterised by diversity in terms of territorial and sectoral layout, depending on the analysed scenario of the COVID-19 pandemic development. It is hard to clearly indicate a macroregion which, irrespective of the scale of the spread of the disease, could be perceived by foreign investors as invariably highly risky or characterised by a constantly low risk of divestment.

    Happy Planet Index
    Gross National Income
    Opis:
    Many of the problems that the world faces today appeared as the result of unstable development. Global climate change, resource depletion, space debris, poverty, inequality, and threats to global security are the main but not the only challenges for modern humanity. The important issue in studying the problems of sustainable development of the countries in the world is the development of strategies that would give an opportunity to avoid environmental and social catastrophes. The correspondence analysis is used to identify the relationship between the Happy Planet Index (which is an aggregate indicator of achievements in the key aspects of human development, such as life duration and quality, distribution uniformity, access to knowledge, and preservation of environment) and Gross National Income (one of the basic metrics of the population welfare level). The analysis led to the conclusion that the income level of the population is not the main factor in assessing the level of sustainable development of a country. The obtained results can give important and useful information for social institutions and politicians.

    Opis:
    The paper aimed at identifying the effects of the coincidence of socio-economic status and the advancement of the family life cycle on the savings rate. The multilevel regression model for data from empirical surveys was used. The obtained results allow us to explain how the differentiation of the saving rate that causes a poor fit of LCH models to the observed reality occurs. Ascribed to this differentiation is the explanation that allows us to reduce the area of unpredictability of the savings rate. These results show that the social representations of saving characteristic for various socio-economic groups are crucial factors that explain the variability of the savings rate, moderating its sensitivity to the demographic factors as defined in the economic theory. Moderation leads to two different tendencies. The first occurs among the households of a relatively low status and lies in the extension of consumption along with age, and it is stronger the lower the status of the household head is. The second, completely reverse, is present among households of a relatively high social status. The contraction of the time horizon of consumption manifests among these households, and it is stronger the higher the socio-economic status of a household head is.

    Opis:
    Nominal data, due to their nature, are often analysed statistically in a quite limited and traditional way. Usually they come from open-ended or simple/multiple choice questions. In typical research projects, such data are often presented in the form of more or less complex tables (including contingency tables) and standard charts. The author’s experience shows that such a visualisation is perceived as boring, especially by younger people, accustomed to the presentation of content in the form of infographics. The article presents examples of data analysis and a visualisation of the nominal data based on the results of the author’s research, including theoretical reflections on the techniques and tools used. The starting point is the raw text data from the responses to the open-ended questions subjected to analyses of the frequency of words and expressions, including its visualisation through word clouds. The next step is categorization and tabulation at the level of individual variables including the visualisation of categories, to assess the contingency between two nominal variables (or the nominal and the ordinal one), including visualising the relationships via chord diagrams and the correspondence analysis.
