Cálculo e interpretación del Alfa de Cronbach para el caso de validación de la consistencia interna de un cuestionario, con dos posibles escalas tipo Likert

Abstract: Three alternatives for calculating Cronbach's alpha were used. These were: by the variance of the items using MS Excel, using SPSS (22) and using the statistical software package free distribution Factor (9.3). These three variants were applied to validate the internal consistency of a questionnaire, with two possible Likert scales, one of five points and another with seven. This questionnaire was designed for the analysis of the criteria for students specializing in Business Administration at the Universidad Central del Ecuador; in connection with the performance of the teacher, the course syllabus, assessment and recommended readings. It is argued that for an effective application of Cronbach alpha should be keep in mind that this coefficient must be considered within the broader problematic of reliability analysis and considerations regarding its application for the use ordinal response scales or Likert scales. The Factor (9.3) package was appropriate to explore relatively simpl
