External validity is the extent to which you can generalize the findings of a study to other situations, people, settings and measures. In other words, can you apply the findings of your study to a broader context? The aim of scientific research is to produce generalizable knowledge about the real world.

Does quantitative research have external validity?

In quantitative research, there are two key types of validity: internal validity and external validity. Internal validity is the extent to which the design and execution of the design are free from bias. External validity is the extent to which the conclusions of a study can be generalised to a wider population.

What is internal and external validity in quantitative research?

Internal validity examines whether the study design, conduct, and analysis answer the research questions without bias. External validity examines whether the study findings can be generalized to other contexts.

What is external validity and example?

Random selection is an important tenet of external validity. For example, a research design, which involves sending out survey questionnaires to students picked at random, displays more external validity than one where the questionnaires are given to friends. This is randomization to improve external validity.

Why is external validity important in quantitative research?

In quantitative research, the concept of external validity is important because we want to be able to say that the conclusions we made in our dissertation can be generalised. We may want to make generalisations (a) to a wider population, and/or (b) across populations, treatments, settings/contexts and time.

What is meant by external validity?

External validity is the extent to which you can generalize the findings of a study to other situations, people, settings and measures. In other words, can you apply the findings of your study to a broader context? The aim of scientific research is to produce generalizable knowledge about the real world.

How do you determine external validity?

Results External validity refers to the question whether results are generalizable to persons other than the population in the original study. The only formal way to establish the external validity would be to repeat the study for that specific target population.

Which best describes external validity?

External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events. The validity of a study is largely determined by the experimental design.

What is internal validity in quantitative research?

The validity of a research study includes two domains: internal and external validity. Internal validity is defined as the extent to which the observed results represent the truth in the population we are studying and, thus, are not due to methodological errors.

How do you know if a study has good external validity?

External validity helps to answer the question: can the research be applied to the “real world”? If your research is applicable to other experiments, settings, people, and times, then external validity is high. If the research cannot be replicated in other situations, external validity is low.

What are the types of validity in quantitative research?

In quantitative research testing for validity and reliability is a given.
Here are the 7 key types of validity in research:

• Face validity.
• Content validity.
• Construct validity.
• Internal validity.
• External validity.
• Statistical conclusion validity.
• Criterion-related validity.

Is validity qualitative or quantitative?

Reliability and validity are conceptualized as trustworthiness, rigor and quality in qualitative paradigm.

Which type of study has the most external validity?

Field experiments

Characteristics of External Validity
For a study to be referred to as having high external validity it would need to be research that can be applied to diverse settings, populations, and time periods. Field experiments tend to have the highest external validity as they can be more generalized to a wider population.
