Validity in Research

What is validity in research?

• The accuracy of the data collected

• Extent to which a study measures what it claims to measure and the degree to which the results can be generalized to the target population.

• The number of participants in the study

• The length of time the study was conducted

What are the types of validity in research?

• internal validity, external validity, construct validity, and statistical conclusion validity

• randomization, blinding, control group, and placebo effect

• reliability, generalizability, accuracy, and precision

• internal validity, external validity, construct validity, and statistical conclusion validity

What is internal validity?

• Extent to which a study provides evidence of a correlation between variables

• Extent to which a study provides evidence of a descriptive relationship between variables

• Extent to which a study provides evidence of a predictive relationship between variables

• Extent to which a study provides evidence of a causal relationship between variables

What is external validity?

• Extent to which findings can be generalized to different populations, settings, or conditions.

• Extent to which findings can be generalized to similar populations, settings, or conditions.

• Extent to which findings can be generalized to unrelated populations, settings, or conditions.

• Extent to which findings can be generalized to other populations, settings, or conditions.

What is construct validity?

• The extent to which a measure or test accurately assesses the theoretical construct or concept it is intended to measure.

• The extent to which a measure or test accurately assesses the practical application of a concept.

• The extent to which a measure or test accurately assesses the external validity of a concept.

• The extent to which a measure or test accurately assesses the reliability of a concept.

What are the threats to validity in research?

• selection bias, measurement bias, confounding variables, and experimenter bias

• recall bias

• response bias

• sampling bias
