How can experimental design avoid bias?
Best practices for minimizing bias in experimental procedures, including: blinding; systematic random sampling; inclusion of positive and negative controls; and methods of quality control for reliability and reproducibility.
How do you get rid of experimental bias?
Both experimenter biases and investigator effects can be controlled by using double-blind experiments which ensures that neither the researcher nor participant knows who is receiving what treatment or intervention.
What type of experimental design can help reduce biases in a study?
Prospective studies (particularly randomized, controlled trials) where the outcome is unknown at time of enrollment are less prone to selection bias.

Section 2: Experimental Studies
True experiments have four elements: manipulation, control , random assignment, and random selection. The most important of these elements are manipulation and control. Manipulation means that something is purposefully changed by the researcher in the environment.
