B. it makes your results more convincing
Explanation:
It is important to conduct multiple trials in an experiment because it makes results more convincing.
Multiple trials removes and spreads error from one or more steps in experiment.
- The ability to reproduce result in an experiment is known as precision.
- Precision is very important in experiments.
- When a scientist carries out multiple trails in an experiment, it helps to remove any likely error that might have been carried into the experiment.
- Multiple trials are key to efficiency of experiments.
- From the results we can confidently state findings based on statistically backed data obtained.

The variable that researchers manipulate is the independent variable.
The reason for this is because in experiments different manipulations are often introduced. The sole purpose of these manipulations is to see whether they will affect our independent variable and if they will change its value.
