A recent commercial advertised for a wristband that claimed to restore health and balance by taking advantage of natural frequen
cies of your biofield. It supports its claim by showing several people first struggling to balance without the wristband and then balancing fine with the wristband. Why should you be skeptical of the claims made in this ad?
The answer is - It was not a controlled experiment
Explanation:
A control experiment can be defined as that in which the all variable is kept constant and intact and then used as a standard of comparison or measurement to the experimental component.The commercial showing several people initially struggling to balance without the wristband and then balancing fine with the wrist band is not a controlled experiment.
