Chi Square Tests

Log-likelihood and Chi-square tests are probably the most popular statistical tests used in corpus linguistics, especially when the research is aiming to describe the lexical variations between corpora. However, because this specific use of the Chi-square test is not valid, it produces far too many significant results. This paper explains the source of the problem (i.e., the non-independence of the observations), the reasons for which the usual solutions are not acceptable and which kinds of statistical test should be used instead. A corpus analysis conducted on the lexical differences between American and British English is then reported, in order to demonstrate the problem and to confirm the adequacy of the proposed solution. The last section presents the commands that can be used with WordSmith Tools, a very popular software for corpus processing, to obtain the necessary data for the adequate tests, as well as a very easy-to-use procedure in R, a free and easy to install statistical software, that performs these tests.

Chi Square Tests

It is widely recognized that t-tests, chi square tests and other statistical tests provide a basis for probability statements only when the hypothesis is fully developed before the data are examined in any way. If even the briefest glance at a study's results moves the investigator to consider a hypothesis not formulated before the study was started, that glance destroys the probability value of the evidence at hand... When either the [statistical] test itself or the reporting of the test is motivated by the data, a probability statement such as "P less than 0.05" is deceptive.

Implementation of IMD in hospitals has decreased from the previous year and has not reached the target set by the government. Some IMD implementation processes have not been carried out according to applicable standards. So that babies do not get an IMD in accordance with existing SOPs. The purpose of this study was to determine the determinant factors associated with the implementation of the IMD by midwives in the Midwifery and Maternity Room Emergency Room (IGD) at the Anutapura General Hospital in Palu. This research method is analytical with cross sectional approach. The population of this study was that all midwives in the obstetrics emergency room and maternity room at Anutapura Palu Hospital were 37 respondents. The sample in this study is total sampling. The analysis used was univariate, and bivariate analysis using the chi square test with a confidence level of 95% (α = 0.05). The results of statistical tests on variable knowledge of midwives with the implementation of IMD p value: 0.018 (p value <0.05). APN training with the implementation of IMD p value: 0.697 (p value> 0.05). length of work with the implementation of IMD p value: 0.029 (p value <0.05). and peer support with the implementation of IMD p value: 0.007 (p value <0.05). Conclusions there is a relationship between knowledge, length of work, peer support with the implementation of the IMD, and training factors that have nothing to do with IMD implementation. The strongest factor in the relationship is peer support. It is recommended that the Anutarapura Palu Hospital be able to motivate midwives so that they can further enhance their role in the implementation and provide support to their colleagues so that the implementation of the IMD can be carried out in accordance with applicable standards.Keywords: Knowledge, APN Training, Duration of work, Implementation of IMD

Although extensively studied, psoriasis still has negative consequences and is associated with multiple comorbidities, including metabolic syndrome. The severity of psoriasis seems to influence the occurrence of diagnostic criteria for metabolic syndrome. 208 patients diagnosed with psoriasis were identified, who were divided into lots depending on the severity of psoriasis, but also to the presence or absence of metabolic syndrome. Interpretation of statistical data was done with SPSS V21 (Statistical Package for Social Science) and MEDCALC (Statistical Software). The coexistence of severe psoriasis with metabolic syndrome increases the risk of developing cardiovascular diseases by 2.97 or greater, with a confidence interval of [1.60, 5.51], than that of patients with severe psoriasis who have no metabolic syndrome. The hypothesis was statistically confirmed by p = 0.003. Analyzing the total group with psoriasis by severity, we found the following distribution: from the total number of 208 patients, 39 (18.8%) had severe psoriasis, 83 (39.9%) moderate psoriasis and 86 (41.3%) mild psoriasis. The higher incidence of metabolic syndrome in patients with psoriasis is evidenced by the Pearson Chi-Square test, where p [0.001. The association of metabolic syndrome in patients with psoriasis is evident. The more severe the psoriasis, the more likely it is to develop metabolic syndrome.

This article aims to confront four theories of firm growth – Optimum Firm Size, Stage Theory of Growth, The Theory of the Growth of the Firm and Dynamic Capabilities – with empirical data derived from a backward-looking longitudinal qualitative case of the growth trajectory of a Brazilian capital goods firm. To do so, we employed Degree of Freedom-Analysis for data analysis. This technique aims to test the empirical strengths of competing theories using statistical tests, in particular Chi-square test. Our results suggest that none of the four theories fully explained the growth of the firm we chose as empirical case. Nevertheless, Dynamic Capabilities was regarded as providing a more satisfactory explanatory power.

Abstract Objective: To analyze the occurrence of Maternal Mortality in general and in the indigenous population in the state of Pará. Method: A quantitative, analytical and retrospective study was performed, covering a historical series from 2005 to 2014. For the analysis of the results, non-parametric statistical tests, the Chi-square test and the G test were processed in the BioStat 5.0 software program. Results: A total of 884 maternal deaths were reported in the state of Pará, corresponding to a Mortality Rate of 60.7 per 100,000 live births for non-indigenous women and 135.8 per 100,000 live births for indigenous women. Oedema, proteinuria and hypertensive disorders in pregnancy, childbirth and puerperium corresponded to 30.5% (n = 270). Conclusion and Implications for the Practice: Maternal mortality remains a serious public health problem in the state of Pará, clearly demonstrating that indigenous pregnant women require greater care, since they showed higher Maternal Mortality Rates when compared to non-indigenous women.

The percentage of families in Lapulu Village that had healthy latrines was 64,84% who met the health requirements and 35,16% who did not meet the health requirements in 2019. This shows that the ownership of healthy latrines is still lower than the national achievement. This study aims to determine the factors associated with low ownership of healthy latrines in the coastal areas of Lapulu Village, Kendari City. The research design was observational, with a cross-sectional approach. The population in this study was 437 respondents, while the study sample was 209 respondents. The sampling technique used was proportional random sampling technique. The analysis were performed using the Chi-Square test. The results of statistical tests with chi-square obtained the value of land availability (p-value=0,000), knowledge (p-value=0,031), and income (p-value=0,000). It can be concluded that there is a relationship between land availability, knowledge, and income levels associated with low ownership of healthy latrines in the tidal area of ​​Lapulu Village, Kendari City. Therefore, it is hoped that the community and local government will establish this inter sector collaboration with related agencies to increase community ownership of healthy latrines.

History Of

Low Born Weigh (LBW) is a baby with a birth weight <2500 grams. LBW babies are weak in fine motor skills. If toddlers' developmental disorders are not detected early it will affect the quality of life, showed the prevalence of LBW by 5.52%. The prevalence of LBW infants in Bantul Regency from 2014 to 2018 has increased. The highest LBW cases were in the Pleret Puskesmas which reached 6.23%. The high prevalence of LBW in Pleret District has made researchers interested in researching the relationship of LBW history with the development of toddlers aged 1-3 years. The purpose of this research is to find out the influence of LBW history on the development of toddlers aged 1-3 years. This type of research is an observational analytic study with a retrospective cohort design. The sample in this study is toddlers aged 1-3 years in the district of Pleret. The independent variables of this study were the birth weight of infants and the dependent variable of development of infants aged 1-3 years. Statistical tests use the Chi-square test and relative risk. This research shows that as many as 31% of children under five with a history of LBW had inappropriate development status. The chi-square test showed a p-value of 0.016 (<0.05) which meant that there was a significant relationship between LBW history and the developmental status of toddlers. Obtained RR value of 1,250 (> 1,00), shows that toddlers with a history of LBW have a risk of experiencing developmental disorders 1.25 times greater than toddlers with normal weight history. The conclusion of this research is a there is a significant relationship between LBW history and the development of toddlers aged 1-3 years. Toddlers with an LBW history have a greater risk of developing developmental disorders compared to toddlers with normal weight history.

Purpose This study aims to identify the competencies of small- and medium-sized enterprises’ (SMEs) entrepreneurs in the software sector and the perceived level of attainment in each competency. It also examines whether these competencies and their levels affect business turnover and growth (in terms of business scale and duration). Design/methodology/approach To accomplish this purpose, the study took a quantitative approach, involving a survey of 33 SME entrepreneurs, which was then processed using statistical tests, including chi-square test, Kruskal–Wallis test and ordinal regression. Findings There were four findings of the study. Firstly, software SME entrepreneurs need 17 competencies, with high levels of soft competencies being required and average levels of technical competencies. Secondly, there are significant differences in perceived levels of customer service orientation (p = 0.089) depending on the scale of the business and in perceived levels of project management (p = 0.087) depending on the duration of the business. Thirdly, customer service orientation (p = 0.031) and project management (p = 0.01) both have a significant influence on business revenues. Fourthly, there were significant gaps in perceived levels of competency (p < 0.05) in achievement orientation, customer service orientation and project management. Originality/value There is existing research that conducts competency mappings at the managerial level in large-scale organizations; however, this sort of research in relation to SME entrepreneurs is still lacking. The present study seeks to fill this gap. It also maps integrated entrepreneurial competencies, including soft and technical competencies; a focus that is lacking in previous studies.
