It is widely accepted that empirical research methods and statistics belong together. This is no different in phraseology. In contrast to the natural and social sciences however, no standardized statistical culture has yet emerged in this field. Empirical research in German phraseology during the last 15 years shows a variety of approaches and analysis methods, which often led to contradictory results. Part of this dilemma can be explained by the fact that statistical methods were ignored, too few participants were involved in the studies, the participants chosen were not representative for the intended group or the statistical tests were improperly used. This article gives a basic introduction to the main statistical tests needed in phraseological research (i. e. chi-square test, t-test, analysis of variance and regression) and clear instructions on when and how to use them. Special attention is drawn to the importance of interactions between different factors (that can be tested with the help of analysis of variance). With this article I hope to have been able to demonstrate that statistics are a necessary tool in phraseology and other linguistic disciplines: on the one hand to organize and to clearly present the data and on the other hand to provide more evidence for regularities in the data.

The Impact

Motivation and employee satisfaction are very important precondition for the effectiveness of work and the achievement of set goals for individuals and organizations. Consequently, continuous measurement of employee motivation and satisfaction is essential to improve company's efficiency and improve human resource use. The results of a well-planned, detailed and adequate methods and techniques of research on employee motivation and satisfaction can be applied to the design of various schemes in order to reduce absenteeism and employee turnover and overall business success. In this paper, the emphasis is on the methodology of researching employee motivation and satisfaction. In addition to the elaboration of questionnaires with scales for measuring the motivation and satisfaction of employees, it is explained in which situations, in which types of questions and answers, respectively, types of data, and how certain statistical techniques are applied, such as: T-test, One-factor analysis of variance (ANOVA), Chi-square test, Point-two-series correlations. Also, the importance of using the subsequent post hoc test (LSD comparison) in the analysis of variance, as well as the indicators of correlation, the strength of the impact, such as: phi correlation coefficient, Kramer's coefficient and contingency coefficient, is pointed out in the Chi-square test. In addition to the mentioned techniques and indicators from SPSS, the role of certain indicators (eta squared and coefficient of determination) is calculated, which are calculated using data from research results and with the help of certain formulas

Abstract Liquefied petroleum gas (LPG) is a widely used environment-friendly fuel. Previous studies have shown an increasing number of LPG-related burns. Our study was designed to evaluate the epidemiologic pattern of these injuries and provide recommendations for burn prevention. This retrospective study included all patients with LPG-related burns from eight burn centers in Zhejiang Province, China between 2011 and 2015. Database variables included patient demographics, accident characteristics, and injury characteristics. The association between different categorical variables was identified using the chi-square test. And the association between two or more means of quantitative variables was analyzed by the one-way analysis of variance or t-test. A total of 1898 patients were included, 47.31% were males and 52.69% were females. The predominant age group was 31 to 70 years (74.50%), and the majority were poorly educated and the incidence peaked from June to September. The most common place of occurrence was home (74.08%) and gas leak (96.52%) was the most common cause. The four limbs (43.33%) were the most frequently affected areas; the mean burn area was 25.19 ± 20.97% of the total body surface area and most patients (46.89%) suffered from moderate burns. The mean length of hospital stay was 17.66 ± 16.55 days and the majority of patients (89.36%) recovered with a 0.84% mortality rate. Our findings reflected that the increase in incidence rate was alarming, and the causes resulting in LPG-related burns have not gained much attention yet. Therefore, this calls for simple but strict measures aiming at each hazardous step during the use of LPG to prevent these burn injuries.

Lifestyle And Physical EducationIn order to improve the influence of Physical Education within schools on the creation of a healthy lifestyle, it is essential to analyze students' opinions in regard to this subject and its teachers. The aim of this research was to establish lifestyle typologies and to find out if these are correlated with the perception of Physical Education and its teachers. The participants in this research consisted of 745 teenagers belonging to three different rural environments. In order to establish typologies related to the use of spare time, a cluster analysis was carried out. Then, the relation between lifestyle and the evaluation of Physical Education was determined by means of the Chi-square test. The results show the existence of two lifestyle typologies. The group with a healthier lifestyle is the one that rates Physical Education and its teachers more positively.

Background: Burning is one of the worst accidents that people may now experience in modern society. One of the most critical problems of burn patients is the anxiety caused by medical treatments such as burn dressing. The present study aimed to determine the effect of rhythmic breathing on the anxiety of dressing change in burn patients. Materials and Methods: This experimental clinical trial was done on 60 burn hospitalized patients in Ayatollah Mousavi educational-therapeutic hospital of Zanjan province in 2017. The sampling was performed continuously and the samples were randomly assigned to control and experimental groups (30 subjects in each group). The data collection tool included a demographic questionnaire and numerical anxiety scale. First, the demographic characteristics questionnaire was completed by the samples. Then, the rhythmic breathing was taught to the experimental group for 20 minutes until complete learning, and they were asked to perform the rhythmic breathing during dressing. Before and after dressing, anxiety was evaluated in the experimental and control groups for 3 consecutive days. After collecting data and entering them into SPSS 20, data were analyzed using descriptive statistics, chi-square test, independent and dependent t test, and Friedman test. Results: Based on the findings of the study, both groups were homogeneous in terms of age, gender, education, percentage and the degree of burn, and there was no statistically significant difference. The results of the Friedman test showed that the anxiety severity had a statistically significant difference in both control and experimental groups before and after the intervention (P<0.001). However, the severity of anxiety after the intervention further reduced in the experimental group compared to the control group, and this reduction was statistically significant in the experimental group (P<0.001). Conclusion: In general, rhythmic breathing is effective in reducing anxiety caused by a dressing change in burn patients. Thus, this method can be used to decrease the anxiety of dressing.

Abstract This article aims to examine the effects of new technology on the purchase of regional brands in Czechia and draw conclusions that will help to adapt the brands to customer needs. Regional brands are a speciality of Central Europe, which emerged due to consumer dissatisfaction with low-quality of global retail products. These traditional local handmade products are heavily influenced by new technology and customers requiring them to be purchasable online with a massive online presence. The sample consisted of 1050 residents of the Czech Republic. The data were gathered by a professional marketing agency Ipsos using a questionnaire survey. The sample was tested using the one-way Chi-square test, which had good compliance to test the basic sample characteristics, followed with the one-sample Kolmogorov-Smirnov test to test the data distribution, and then, the dependencies were tested with the Kruskal-Wallis test. Finally, a post-hoc test suitable for the type of analysis could be chosen to better understand the type of factors that could influence the results and their possible effect. The main findings indicate a slow change in the demand as customers are neutral in relation to regional brands available from online shops as well as their about social media presence but require them to have a good-quality website. Solutions are proposed using a government-run brand with a platform providing web layouts and hybrid e-shop. The type of content is proposed, indicating the appropriate execution, which should be done based on the researched-derived segmentation criteria.
