1. Validity : The experimental setup was good. The experiment measures what it claims to measure.  

2. Reliability : The results will be the same if the experiment is repeated by others

3. Peer Review: Scientists read and review each other’s work by using peer reviewed scientific journal

4. Bias: The tendency to favor some results or explanation over others. 

Researchers wanted to investigate how different amounts of water affect seed germination. They took 20 identical bean seeds and divided them into two groups: Group A received the normal amount of water daily (1 gallon), while Group B received 2 gallons of water . After one week, the researchers recorded how many seeds had germinated in each group.
