Research Design:

-Exploratory

-Conclusive

Exploratory

-Causal

-Descriptive

Causal

-Independent variable

-Dependent variable

Test units:

Extraneous variables:

Variables other than the independent , that which can affect the dependent variable;

Conditions for Causality:

Concomitant variation : Y and X vary together

Time order of occurrence : Y has to happen after X

Absence of other possible causal factors:

What is experimental Design?

Which of the dependent variables manipulated?

what are the extraneous variables to be considered?

How do you control the effect of extraneous variables?

How do you measure the dependent variable

Internal validity:

Refers to the certainty that the observed variation in dependent variable is only due to independent variables , and no extraneous factors exist
