Prueba Anova para datos no Paramétricos de Friedman en JASP

Sánchez Acero Francisco Alejandro | 2020-07-27

The Friedman test is used with data that does not behave normally and / or with ordinal data, this test allows identifying if there is a significant difference between the different states of the subject. Along with this test they were accompanied by a post-hoc test that allows verifying whether or not there are differences between couples.

Análisis Descriptivos en JASP

Sánchez Acero Francisco Alejandro | 2020-07-27

Descriptive statistics allow a careful observation of the behavior of the variables worked in a population, writing these variables allows making correct decisions compared to what happens in a specific population. Descriptive statistics contributes to different fields of knowledge detailing and events that are not so easily seen when working a database.

Prueba Chicuadrado

Sánchez Acero Francisco Alejandro | 2020-07-27

The chi-square test allows observing whether or not there is a relationship between two qualitative variables, for this it´s necessary to obtain information on the observed values ​​and the expected values, with this information the experimental chi-square value can be obtained, which is carried out pending the determined calculation for this, and then it is necessary to contrast it with the critical value given in the table, identifying the confidence value and its comparison. In the end, a decision can be made by observing if this experimental value is greater than the critical one. It would be concluded that the null hypothesis is rejected, which allows solving the given problem.

Pruebas Paramétricas y No Paramétricas

Sánchez Acero Francisco Alejandro | 2020-07-27

Las pruebas Paramétricas y No paramétircas se identifican mediante la prueba base de normalidad de las variables a trabajar. En el diseño se planteas dos tipos de estudios los transversales los cuales se encargan de comparar varios grupos de diferente naturaleza, los longitudinales los cuales permiten comparar un mismo individuo en varios momentos o tiempos. Para las pruebas Transversales se analizan sus variables si estas son de intervalo o de razón y son normales se aplicará pruebas paramédicas, de lo contrario se aplicarán las pruebas no parametricas. Entre ellas se encuentran la pruebas T de Student, Anova, Chicuadrado , U Mann Withney, Q de Cochran, Fridman, Wilconxon entre otras.

Variables y Niveles de Medición

Sanchez Acero, Francisco Alejandro | 2020-07-21

Variables can be determined in different ways: quantitative or qualitative; discrete or continuous and in its various levels of measurement, nominal, ordinal, interval or ratio. Depending on their classification and operationalization, they can be measured or decisions can be made. The basic characteristics between the measurement levels are: identity, order, distance and the value of 0. In all cases it is necessary to determine their nature in order to identify the analyzes to be carried out.
