Question

damian tests the number of identical paper clips a small magnet can pick up. he tests the magnet three times and records his results. he then repeats the process for two other magnets, which are different sizes. his results are shown in the table below. which of the following best explains the importance of performing three trials? three trials will allow him to obtain more data points. three trials will help him to choose the data that best supports his hypothesis. three trials will prove whether a magnets strength can change. three trials will enable him to draw valid conclusions.

Explanation:

In scientific experiments, multiple trials reduce the impact of random errors and outliers. By conducting three trials, Damian can calculate an average, which gives a more accurate representation of the magnet's performance. This helps in drawing valid conclusions about the relationship between magnet size and the number of paper - clips picked up.

Answer:

Three trials will enable him to draw valid conclusions.
