How could increasing the number of plants help
you decrease error in the experiment? Check all
possible reasons.
It would increase the sampling error.
It would reduce the significance of any single
measurement error.
It would make calculations easier.
Having more data would make the average
height less affected by one or two plants that
are randomly shorter or taller
It would make a plant's death less of an
issue

Explanation:

This is akin to reducing the significant error of a sample. The more the sample is representative of the whole population the less the sampling error.   More plants increase the sample size and reduce the skewness of the data, by improving the margin or error, making it more representative of the population in study in the experiment.
