Final answer:

Statistically designed experiments include comparing treatments and assigning subjects randomly to treatment groups while maintaining blinding to prevent bias.


Explanation:

Two essential features of all statistically designed experiments are the comparison of several treatments and chance to assign subjects to treatments. In a well-designed study, subjects are randomly assigned to different treatment groups to eliminate lurking variables, with one group acting as a control group that receives a placebo treatment. The double-blind method ensures that both researchers and subjects are unaware of who is in the control or experimental group to prevent bias.
