Darren performed an experiment in which he measured the amount of force that was required to accelerate an object at a rate of 5 m/s2. then, he repeated his experiment four more times and calculated the average force that was needed. why did darren repeat his experiment? a. because all experiments are required to perform exactly five trials b. to figure out which procedure was best to use c. because he made a mistake in each of his previous trials d. to increase the reliability of his data

D. to increase the reliability of his data

Explanation:

For an experiment to be considerably reliable, it must be repeated and the same results must be visualized in all repetitions. This indicates that the experiment was performed correctly and that its results are reliable and replicable. If in one of the repetitions of the experiment a different result is visualized, it means that something is incorrect and the researcher should look for what is taking the reliability of his study.

For this reason, we can say that Darren repeated his experiment four times to increase the reliability of his data.

youre right there are
