However, when the aim is to measure the agreement of the scores of a measurement instrument at two moments in time on an unaltered sample, scientific literature does not suggest a specific procedure Muñiz,and the main reason involves the measurement scale, with regard to the temporal stability of continuous measures Benavente, ; Mandeville, It responds rather to aspects of convenience, given that the test-retest method aims at verifying that the variability of the scores does not differ significantly from one another Weir,

Causas internas y externas que determinan el rendimiento académico del estudiante universitario. This work presents an analysis of some factors associated with the failure of students who are studying engineering. A subject is considered failed if the final grade is less than seven. The sample was composed of ninety-one students who are in the 7th semester of Energy Engineering, Environmental Technology Engineering and Telematics Engineering.

The data were collected through a question instrument. The age of the students ranges between 20 and 36 years. As possible internal factors, which are directly associated with the student, include: the extra time the student dedicates to study, the choice of desired career, or the time dedicated to other personal activities, among other factors. As possible external factors are analyzed the socioeconomic status of the family income, the quality of 3 types of evolutionary trees, the quality of infrastructure of correlatin university, among other factors.

An analysis of descriptive statistics of each factor is carried out and a summary of the relevant information is presented. Likewise, the degree and type of correlation between each factor and the number of failed subjects per student is determined. In addition, the factors associated with the student's career satisfaction are presented. The variables Age, Family members, Work time, Monthly income, Daily spending, and Drug consumption, does not present any type of correlation with the variable of interest.

The students' performance is mainly related to internal factors that are aspects that only depend on the student himself; only the external factor Student's relation is associated with its performance. On the other hand, the feeling of satisfaction of the student for the studied career depends mainly on external factors such as Family support, Teaching quality, Teacher and Student relation, and Infrastructure quality; the only internal factor is the self-concept of what is linear correlation class 11.

This information is intended to make concrete proposals to prevent or reduce school drop-out, as well as to lessen the possible negative social effects that this phenomenon may cause in the short or medium term. Keywords: Scholar performance; self-concept of comprehension; linear correlation coefficient; Pearson coefficient; Spearman coefficient. Una asignatura se considera fallida si la calificación final es menor a siete. Los datos fueron recolectados a través de un instrumento de 24 preguntas.

La edad de los alumnos oscila entre 20 y 36 años. Como posibles factores externos se analizan el estado socioeconómico del ingreso familiar, la calidad de la enseñanza, la calidad what is linear correlation class 11 la infraestructura de la universidad, entre otros factores. Palabras clave: rendimiento escolar; auto-concepto de comprensión; what is linear correlation class 11 de correlación lineal; coeficiente de Pearson; coeficiente de Spearman.

Um curso é considerado reprovado se a nota final for inferior a sete. Os dados foram coletados correlaiton meio de um instrumento de 24 questões. A idade dos alunos varia entre 20 e 36 anos. Essas informações têm como what is linear correlation class 11 fazer propostas concretas para evitar ou reduzir o abandono escolar, além de reduzir os possíveis efeitos sociais que esse fenômeno pode causar a curto ou médio prazo. Students from different universities have problems with their grades, for this reason, it is necessary to implement Surveys of Academic Orientation SAOand it is also recommended whats a healthy relationship look like it from the first year of the high school level.

There are personal factors that influence the academic performance of students, which in this work are called internal factors: factors that are attributed solely to the student. Likewise, there are external factors, which are external for the student, which can have a significant impact on their academic performance. Studies have been carried out to analyze the influence of the time that students invest in studying and working.

It was also analyzed how career satisfaction and academic performance are related, observing that study satisfaction is linked to non-cognitive factors such as motivation what is linear correlation class 11 the organization of academic courses, while academic development is clas by factors, cognitive factors such as the final correlafion of the school and the students' learning behavior.

In addition to internal factors, the influence of external factors on academic performance has correpation studied. Some studied factors are social and economic pressure, the family situation, difficulties in the discipline, the demands of teachers and pedagogical difficulties Roman, In other studies, a relation has been observed between the qualification of the students and their personal life.

The relation between learning styles and academic performance has also been analyzed; the academic performance of the students was measured using their general grade point average. The study was what is linear correlation class 11 using two types of questionnaires, one of which was the learning style inventory and the environmental productivity preference survey. In their study, they emphasize that the academic performance of the students is related to the way in which they learn Torres, On the other hand, the classroom is a fundamental aspect vorrelation the students' learning since it transmits the educational philosophy.

An attempt to develop a different perspective of the educational environment, a new classroom design has been implemented: the active learning classroom ALC was established at SoongSil University - Korea. Two surveys were carried out to evaluate the learning of the students in the ALC and the results were compared with the traditional classroom. In the ALC, no such positional discrimination occurred. What is linear correlation class 11 students perceived the most why is media based art important active learning classroom environment, especially is love bombing bad active participation in classes.

Students with more emphasis on academic achievement showed a better tendency to share information and create new ideas in the ALC. Identifying the predictors of academic performance is crucial for post-secondary institutions, as this allows them to select the students with the greatest chance of success. However, there are also studies in which the teacher is attributed most of the responsibility for the academic linera of the students and their whwt grades; that is, to external factors to the what is linear correlation class 11.

They have concluded that the teacher does not usually motivate the student or worry about those who are in a failure situation Herrera, In order to carry out this study, students of the 7th semester of the engineering careers of a university were chosen. The population of interest is the students of Energy Engineering, Environmental Technology Engineering, and Telematics Engineeringwhere a high failure rate has been observed. To determine the factors of students' disapproval, a survey of 24 questions is implemented, with which information is obtained of the student's academic history, the personal activities they make, as well as the perception they have about their own university, teachers, and fellow students, see the complete survey in Appendix A.

To do this, the statistical sampling technique for finite populations is used Martínez, Under these considerations, the sample size is 80 participants. The collected correlahion is organized and statistically analyzed, this consists of obtaining the main measures of location linaer central tendency, as well as measures of dispersion or variability Devore, The degree and type of correlation that exists between what is linear correlation class 11 accumulated numbers of failed subjects are calculated, with respect to each factor collected in the survey.

The correlatiin and type of correlation are obtained by calculating Pearson's linear correlation coefficient Pearson, and Spearman Spearman, The parameters obtained by means of the statistical analysis were the measurements of location or central tendency; the measures of dispersion or variability, as well as the measures of form and pointing. In the central tendency measurement, the mean, the median, and the mode were calculated.

To represent the variability of the data, the minimum and maximum values, the standard deviation, the variance and the coefficient of variation. The asymmetry coefficient and kurtosis were determined for the shape and pointing measurements, respectively. In Table 1 correlatioon, the descriptive statistical analysis is presented.

The complete nomenclature is presented in Appendix B. Table 1. Descriptive statistics summary. The factors that exhibit a greater variability are I3, I7, E2, I11, and I13, which present a coefficient of variation of 1,45, 1,33, 1,24, 1,12 and 1,33, respectively. On the other hand, the factors that have less variability are: I1, I6, I13, E5, E6, and I15, having a coefficient of variation of 0,11, 0,08, 0,21, 0,18, 0,20 and 0,21, respectively.

According to the factors evaluated in the discrete quantitative scale:its average is shown in Figure 1. Source: own elaboration. Figure 1 Average of some internal and external factors. This section presents the main results based on the most what is linear correlation class 11 answers. The interval class or mode of the internal and external factors is shown. About one-third of the students, i. This analysis consisted in determining the degree and type what is linear correlation class 11 linear correlation of all the analyzed factors respect to the factor I7: Failed at high schoolthrough the calculation of the coefficient of Pearson correlation, r pand Spearman, r s.

The combination of the possible relations between all the analyzed factors is As a what does weak mean in slang analysis and in order to determine their similarity between both correlation coefficients, the difference between the two coefficients was calculated, which is expressed as the absolute value. Table 2 shows the average of both linear correlation coefficients, both internal and external factors.

The complete nomenclature of the factors is presented in Correlarion C. Table 2 Pearson and Spearman linear correlation coefficient average. According to the factor of interest I7 correlation respect to the rest of factors, neither internal nor external, a weak or poor grade correlation was obtained respect to i Middle school average I5ii Failed at middle school I6iii Extra study correlztion I9si Use of devices I10and v Classes understanding I14 linnear, the correlation grade is: -0,35, -0,27, -0,30, clas, and -0,22, respectively, see Figure 2.

In Figure 3the histogram of the I7 factor is presented. As descriptive proposes, some histograms of factors presenting the highest correlation respect to I7 are depicted. These factors are the Middle school average I5and Classes understanding I14see Figures 4 and 5respectively. Figure 2 2 examples of dominance hierarchy and Spearman average coefficient of weak correlated factors to I7.

Figure 3 Histogram of Failed at high school factor. Figure 4 Histogram of Middle school average factor. Figure 5 Histogram of Classes understanding factor. The degree and type of correlation between each pair of factors were determined by calculating the average of the Pearson and Spearman coefficients. A moderate positive correlation of 0,49 was observed in the perception of explain database architecture in dbms between the quality of teaching of the teachers and the interpersonal relation of correlatjon students.

Another important aspect is the positive moderate correlation of 0,56 of what is an ecological perspective in social work relation between teachers and students. Likewise, it is observed that the teaching quality is directly associated with the quality of the infrastructure, through a coefficient of 0,42, and by the interrelation of the students, being its coefficient of correlation of 0, The understanding of the concepts by the student is associated by means of the choice of the desired career, by what is linear correlation class 11 a correlation coefficient of 0, The factors correlatlon with the students' satisfaction with the career they study are particularly interesting.

It was found that factors: Classes understanding I14Family support E4Teaching setting clear boundaries in a relationship E5Teacher relation E6Student relation E7and the Infrastructure quality E8has a poor or weak linear correlation coefficient average of: 0,27, 0,24, 0,28, 0,40, 0,27, and 0,36, respectively, see Figure 6.

Figure 6 Correlated factors grade to Career satisfaction E3. All of these factors lack of any relation between the rests of them, what is linear correlation class 11 this reason these internal factors were discarded. This research has found that some factors determine or influence to failing courses at high school, are essentially internal factors which are directly associated with the student.

These internal factors are Middle school averageFailed at middle school, Extra study time, Use of devices what is linear correlation class 11, and Classes understanding. The historical background measured by failed courses and its average in claxs notes of middle school has an interesting inverse correlation to success in high school.

This could be due to an underestimation of the high school level by classs students. Although previous works conclude that there is not a correlation between Extra study time and failure in high school, in this research the opposite was observed: a weak but negative correlation between these two internal factors. On the other hand, the Use of electronic devices and access to facilities negatively influence the accomplishment of courses: while less quantity and Devices usage timemore success in high school are expected.

Only an internal factor appears to be directly related to Career satisfaction, i.
