My latest lecture in research and experimental study designs. The randomized controlled trial is the famous example of experimental study designs. The various types, strengths and limitations of RCTs are clearly described in this lecture.

Step 3-3: Experimental Study Designs and RCTs. ممكن تشتغل عليه Study design أهم In this lecture, i described the experimental study designs in which the investigators investigate and introduced intervention whether a drug or a technique....

Observational study designs investigate the relationship between an exposure and outcome. Whereas, experimental study designs investigate the relationship between an intervention and outcome. The exposure might be a risk factor or a disease you observe. An intervention might be a drug you administer or a technique you perform.
In this lecture, I described the different types of observational study designs, strengths and limitations of each type.

Step 3-2: Observational study designs; types, strengths, and limitations. This lecture represents the second lecture in step 3 of the research process in which we will choose the study design that best suits your research objective...
