A student measured the power of a motor operating at different temperatures. The student recorded a total of 11 measurements, one at each two degree interval between 10 degrees Celsius and 30 degrees Celsius. Which change in the procedure would most improve the validity of conclusions based on this investigation?

A. Decreasing the range of the IV

B. Repeating the experiment several times

C. Increasing the # of variables

D. Producing a graph of numerical observations

Repeating the experiment several times would most improve the validity of conclusions based on this investigation. Option B is correct.

What is electric power?

Electric power is the product of the voltage and current. Its unit is the watt. It is the rate of the electric work done.

The formula for the power is given as;

P=VI

Where,

V is the voltage

I is the electric current

P is electric power

A modification in technique would greatly improve the validity of the results reached as a result of this research.

Repeating the experiment many times would most improve the validity of conclusions based on this investigation.

Hence,option D is correct.
