Content: Dr. Petiti’s lecture was about validating any research method. The outcomes from any research can come in different shape and terms. It can be measured in terms of mean, risk/odd ratio or hazard ratio. A research study is valid as long as it finds the truths. There are 2 types of validity – internal and external. Internal validity researches with the design method of the study and the measurement analysis, where the latter validates the difference in applicability to person to person or place to place.
