Comprensión de la distribución muestral mediante configuraciones didácticas y su implicación en la inferencia estadística

We present a study on the understanding of sampling distributions and their connection with parameter estimation by confidence intervals. The teaching of statistical concepts, aimed at university students, is based on the implementation of settings configurations. Was applied two open problems and a questionnaire on confidence intervals Olivo, Batanero and Diaz (2008) to a group of 113 students. The results indicate improvements in the understanding of the estimated parameters, the coefficients relating to trust and choosing the appropriate sampling distribution to construct con-fidence intervals. In addition, the findings algebraic procedural difficulties of sampling distributions.
