The addition of another person at each end of the rope does not affect the results of the tug of war.
The addition of another man at each end of the rope does not affect the results of the tug of war because the forces exerted by each individual are independent of each other.
In a tug of war, the force applied by each person depends on their individual strength and the technique used to pull the rope.
The total force exerted on the rope is the sum of the individual forces, and it remains the same regardless of the number of people at each end.

Three ways that scientist can use to avoid bias are;
- Sampling method
- Using blind study
- Repetition
Explanation;
Sampling method involves the studying of a small quantity of a particular aspect in order to form an opinion about the whole population. To avoid bias its important to obtain samples that are appropriate and that would cover the entire participants studied.
-Repetition involves repeating a particular experiment several times in order to ensure that one gets the same results that is ensure accuracy of the results.
-Blind study involves an experiment in which the control and the variable groups are conceal from the participants until after the end of the experiment. It is an important factor to avoid bias in scientific research.
Scientists can minimize bias in scientific investigations through randomization, blind studies, and double-blind studies.
There are three ways that scientists can minimize bias in scientific investigations:
