Estadística

La estadística se ocupa de recolectar, organizar y analizar datos para obtener
información. Los datos se recolectan a través de encuestas y se organizan en tablas o
gráficos.

Para realizar una estadística necesitamos:

 POBLACION: Conjunto de individuos a encuestar. EJ: personas, animales,
cosas, etc.
 MUESTRA: Cantidad de individuos a encuestar. EJ: 30 personas.
 VARIANTE: Tema sobre el que vamos a encuestar. Se clasifica según las
respuestas obtenidas:

Cualitativa: Son las respuestas no numéricas, es decir,
cualidades o características. EJ: equipo de futbol.
Cuantitativa: Son las respuestas numéricas. EJ: la edad.

Ejemplo:
Se hace una encuesta a un grupo de estudiantes de una
escuela, donde en el curso son 30. Se quiere saber cuál es la
materia favorita y cuál es la nota más alta.
 Población: grupo de estudiantes.
 Muestra: 30 alumnos.
 Variante: materia favorita: cualitativa
Nota más alta: cuantitativa
