Testing Device is Needed in Conducting Research

 In conducting any research either science or non science, testing device is really needed. Without a testing device you cannot measure or prove the claim you wanted. There is really a need of using a testing device like if you are conducting a study about bacteria a hemocytometer  would be needed to count the number of bacteria present in your experimental and control systems and if you're studying force, torque or power a dynometer also known as dyno can do the measuring. For nonscience research, the use of rubric for measuring behavior is advised. Never conduct a research with out anticipating what instrument or device to measure or to prove your hypothesis or else you would be wasting your time and effort.
