distinguish between reliability and validity in research design

This type of validity estimates whether the given experiment actually mimics the claims that are being verified. This validity ensures that the test or questionnaire that is prepared completely covers all aspects of the variable being studied. Divergent or Discriminant Validity– It ensures that if the required theory predicts that one variable doesn’t correlate with others, then statistics need to confirm this. Convergent Validity– It ensures that if the required theory predicts that one measure is correlated with the other, then the statistics confirm this.ī.

Construct validity is further divided into 2 types:Ī.

It provides a clearer image of what people think of a certain issue.

It is reflected by a questionnaire regarding public opinion.

It ensures that the actual experimentation and data collection conforms to the theory that is being studied.

Statistical validities relevant to research are broadly classified into 6 categories: 1. What Are the Different Types of Statistical Validities?

Furthermore, it also allows the researcher to optimize the number of assays and satisfy the validation criteria of a study.

It allows the researcher to ensure the validity of research based on its criteria of method selection.

The researcher understands whether a method of analysis is suitable for its intended use to derive conclusive results.

It increases the probability of research reproducibility.

It allows the analyst to know whether the results of the conducted experiments can be accepted with confidence or not.

It is important to determine statistical validity of research data because

Why Is It Important to Determine Statistical Validity of Research Data? Thus, if a given data set draws a conclusion after experimentation, it is said to be scientifically valid and relies on the mathematical and statistical laws of the principal study. To achieve statistical validity, it is essential for researchers to have sufficient data and also choose the right statistical approach to analyze that data.įurthermore, statistical validity also refers to whether statistics derived from a research study are in agreement with its scientific laws. Statistical validity can be defined as the extent to which drawn conclusions of a research study can be considered accurate and reliable from a statistical test.
