two concepts concerning the validity of an experiment are known as external validity and internal validity. The relationship between these two ideas can be described as inversely proportional (Huitt, Hummel, & Kaeck, 1999). A copious amount of factors contributes to the role of internal and external validity. This statement causes the amounts of external and internal validity change with various trials of an experimental procedure. The definition of internal validity is the approximate truth concerning
alter the validity from being just a psychological test to be a psychological experiment, validity had been distinguished into two main categories the first was the internal validity experiment and the other was the external validity these two main domains were the one which transferred to Economics, the continuous work on validity had led Francesco Guala to more specific and analytics definition of the internal experiment.

This easy-to-remember acronym is a great way for journalists to quickly know if the information they are looking at is a good source of information for their research.

This analysis provides assessment of the theory measured by using the empirical evidence of the validity of the items based on overall fitness of the model and the construct validity (Hair et al., 2010). A measurement theory refers to a set of theoretical, systematic, and logical assumptions that suggests path between underlying constructs and items. The construct validity is the fundamental requirement for testing the theory further (Carmines and Zeller, 1979; Steenkamp and Trijp,
of the study were examined using exploratory factor analysis, content validity, concurrent validity and internal consistency reliability. This study has confirmed an empirical relationship between the ten dimensions of safety climate and two outcome variables: safety satisfaction and feedback, and safety incidents. All the constructs demonstrated an acceptable internal consistency. The instrument also confirmed a rational validity in assessing what they are supposed to measure. In conclusion, consistent
of literature findings. Then the framework was assessed and refined using a series of quantitative techniques, specifically Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), Structural Equation Modelling (SEM), and nomological validity. These techniques were conducted based on the data obtained from a questionnaire survey of Malaysian e-government. The current study contributed to existing knowledge by providing a valid and reliable socio-technical security measurement framework
