Se analiza las Actitudes hacia la Estadística en estudiantes universitarios que llevan un primer curso de Estadística en el marco del programa Estudiante Adulto, Trabajador de una universidad privada de Lima en Perú. Son consideradas dos escalas: Actitudes hacia la Estadística de Estrada (2002) (AEE) y Actitudes hacia la Estadística de Cazorla; Silva; Vendramini & Brito (1999) (AEC). La muestra corresponde a 137 estudiantes de cuatro especialidades de Ingeniería, con edades entre 32 y 42 años, siendo un 84 % del sexo masculino y un 52 % que ya habían llevado antes un curso de Estadística. El análisis de ítems fue realizado considerando la Teoría Clásica de los Test (TCT) y la Teoría de Respuesta al Ítem (TRI), bajo inferencia bayesiana del Modelo de Respuesta Graduada de Samejima (Tarazona, 2013).Los resultados muestran que AEC tiene una confiabilidad de 0,93; en c...

This paper studies the attitudes of college students concerning statistics; students who aretaking the basic course in Statistics under an Adult Worker Student program at a private university in Lima, Peru. Two scales have been considered: Attitudes Toward Statistics (ATSE) proposed byEstrada (2002) and Attitudes Toward Statistics (ATSC) proposed by Cazorla et al (1999).The sample corresponds to 137 students with ages ranging from 32 to 42 years old, fromfour engineering majors, , 84% male and 52% who had taken a previous course in statistics.The item analysis was performed considering the Classical Test Theory (CTT) and ItemResponse Theory (IRT) under the Bayesian inference of the Samejima’s graded response model(Tarazona, 2013).The results reveal that AEC has a reliability of 0.93, and by comparison a shortened versionof AEE after eliminating two items has a reliability of 0.88. Bot...

Los modelos politómicos de la Teoría de Respuesta al Ítem (TRIP) tienen como finalidad explicar la interacción existente entre los sujetos evaluados y los atributos de un test en aquellas situaciones en las cuales los atributos que lo componen tienen varias categorías de respuesta. Dentro de los distintos tipos de modelos TRIP, el Modelo de Respuesta Graduada General (GRM) propuesto originalmente por Samejima (1969, 2010), es un conjunto de modelos diseñados para aplicarse en aquellas situaciones en las cuales las categorías de respuesta son ordinales. En este trabajo se presenta una formulación general para los GRM, su clasificación y principales propiedades desde el punto de vista bayesiano. De manera específica, se muestra el Modelo de Respuesta Graduada Logístico de dos parámetros (2PL-GRM) como un caso particular de los GRM simétricos y el Modelo de Respuesta Graduada L...

The present study’s aim is to design, construct and validate an instrument that allows for the measurement of the dimensions for short break tourist destination. The instrument was comprised of 29 items that were applied to 400 university students from diverse undergraduate in Lima, Peru through a convenience sampling. The analysis of the psychometric properties of the instruments and the construction of the perception scale of the short break destinations was carried out through application of Exploratory Factor Analysis and the Graduated Response Model from Item Response Theory. The results show a valid and reliable scale to measure a short break tourist destination. Moreover, show that evaluated individuals tend to positively rate the attributes of the short break destinations they have visited and that tourist perceive the measured attributes as expected characteristic when they vi...

Globalization and changing lifestyles are generating new forms of tourism, including visits to short break destinations. The objective of this study is to propose a definition of short break destinations and to present the dimensions of the attractiveness of tourist destinations. The methodology consisted of reviewing the literature of 64 academic publications. The result shows the determinants that should be considered in the definition of short break destination and the following dimension are proposed: 1) naturals resources, 2) cultural and historical resources, 3) social factors, 4) tourist services and 5) infrastructure.

Researchers have explored the antecedents and consequences of recovery satisfaction by creating, improving or using scales. However, scales should be invariant among contexts and cultures. Using item response theory, a methodological approach that helps measure items, we evaluated some constructs related to it. Results, limitations and future research are discussed.
