A student wants to test the effect of fertilizer on plant growth. She will grow one plant without fertilizer as a control. Why should she perform her experiment with the fertilizer on multiple plants instead of on just one plant?
Using many repeated trials shows that her results are reproducible.
Using many repeated trials will enable her to see whether the amount of sunlight has any effect.
Using many repeated trials shows that no one else can reproduce her results.
She should not use multiple plants, one plant is enough.
