Final answer:
Data can support or reject a hypothesis but can never prove it conclusively. More evidence supporting a hypothesis increases its likelihood of being true.
Step-by-step explanation:
Data can support or reject a hypothesis but never prove it because a hypothesis cannot be proven conclusively true. When conducting experiments, scientists collect data that will help them draw conclusions about the phenomenon they are studying. If the data collected matches the expected observations, it supports the hypothesis. However, it is important to note that more evidence supporting a hypothesis increases its likelihood of being true, but it can never be proven beyond a shadow of a doubt.
