Strict study protocol: Following specific procedures during the study so as not to introduce any unintended effects for example, doing things differently with one group of study participants than you do with another group.Randomization or random assignment: Randomly assigning participants to treatment and control groups, ensuring that there is no systematic bias between the research groups.Random selection: Choosing participants at random or in a manner in which they are representative of the population that you wish to study. Experimental manipulation: Manipulating an independent variable in a study (for instance, giving smokers a cessation program) instead of just observing an association without conducting any intervention (examining the relationship between exercise and smoking behavior).Blinding: Participants-and sometimes researchers-are unaware of what intervention they are receiving (such as using a placebo on some subjects in a medication study) to avoid having this knowledge bias their perceptions and behaviors, thus impacting the study's outcome.
