¿Qué es una variable?

Son características de la realidad que pueden ser determinadas por observación/medición.

Pueden mostrar diferentes valores de una unidad de observación a otra, (persona, páis, ambiente)EJ: edad, ingresos, número de habitantes, apego a las normas, rendimiento académico

Page 3: Variables

Tipos de variables

Dependientes e independientes

Relación de dependencia y causalidad

El valor de una determina el valor de la otra

la variable independiente “causa” la variable dependiente

el comportamiento de la variable dependiente se podría predecir sobre la base del comportamiento de la variable

independiente.

Page 4: Variables

Independientes (VI) “x”…

Es manipulada por el investigador con el objeto de estudiar cómo incide sobre la variable dependiente.

Variable explicativa

Page 5: Variables

Dependientes (VD) “y”…

Varían según la modificación de la Variable Independiente.Variable explicada.Si se da x entonces se da Y“Si aumenta el salario docente (x), aumenta la cantidad de docentes en el sistema (y)”
