Análisis de datos sobre el estudio de la contaminación por ruido en el comportamiento y sistema nervioso usando como modelo experimental, al cangrejo ermitaño (Coenobita clypeatus)

El módulo tiene como meta familiarizar al estudiante con estrategias y métodos utilizados para el análisis de experimentos conductuales y moleculares como “Western blots” e inmunohistoquímica con florescencia. El módulo describe el proceso de análisis de los datos cualitativos y cuantitativos del estudio. Un proceso de análisis de tres pasos será descrito en el módulo. Los pasos del proceso de análisis de los datos son:

  1. La recolección y la preparación de los datos del estudio;
  2. El análisis descriptivo de los datos; y
  3. El análisis inferencial de los datos.

Estos pasos pueden completarse en serie y en algunos casos de manera concurrente.

Objetivos de aprendizaje del módulo: 

  1. Describir las estrategias y los métodos utilizados para recolectar datos de los experimentos conductuales del estudio.
  2. Describir las estrategias y los métodos utilizados para recolectar datos de los experimentos moleculares (Inmunohistoquímica y “Westerns blots”).
  3. Mencionar cómo documentar y organizar los datos. 
  4. Describir los datos del estudio como cuantitativos y/o cualitativos.
  5. Definir la estadística descriptiva.
  6. Definir las medidas de tendencia central, distribución normal, desviación estándar y SEM.
  7. Describir la representación gráfica de los datos cuantitativos y cualitativos del estudio.
  8. Describir los conceptos básicos del análisis inferencial de los datos usando el modelo estadístico de varianza de un solo factor, también conocido como “One-Way ANOVA” y las pruebas de comparación múltiple que se utilizarán para el análisis estadístico de los datos cuantitativos del estudio.
