Question

question 1 - 5
alexis wants to determine whether the size of a magnet affects its magnetic properties. she hypothesizes that the larger the magnet, the stronger the magnetic attraction. alexis designs an experiment using three different - sized magnets to test her hypothesis. she holds each of the three magnets over a container of paperclips to see how many paperclips each magnet will pick up. her results are shown in the data table below.
the effect of magnet size on magnetic properties

size of magnet	number of paperclips attracted
small	5	6	5	5.33
medium	4	2	9	5.00
large	3	8	5	5.33

what should alexis do next after examining her experimental results?
alexis should change her hypothesis to match the data she collected.
alexis should discard her data because it doesnt support her hypothesis.
alexis should conclude that larger magnets always have a stronger magnetic attraction.
alexis should conduct more trials to determine whether the difference in her data is significant.

Explanation:

In science, more trials help assess data significance. Changing hypothesis or discarding data wrongly, and current data doesn't strongly support conclusion.

Answer:

Alexis should conduct more trials to determine whether the difference in her data is significant.
