alicia conducted an experiment to find out which insulating material holds in the most heat. she did multiple trials of each test and recorded observations of each trial.

why did alicia most likely do more than one trial? check all that apply.

to increase the reliability of her data

to provide a better understanding of the concepts she investigated

to prevent other people from using the data incorrectly

to in arriving at a conclusion even with inaccurate data

to reduce the likelihood of errors in the experiment

Option A, to increase the reliability of her data

Explanation:

The larger the number of trials, the higher is the chance to eliminate mistakes occurring in observation. The lesser is the mistake, the more reliable is the result.  

Sometime the same result is depicted in all the trials, even though certain number of trials is required to ensure the correctness of the procedure followed for the experiment.  

Hence, option A is correct

A.to increase the reliability of her data

B.to provide a better understanding of the concepts she investigated

E.to reduce the likelihood of errors in the experiment
