When scientists conduct investigations, they collaborate to support each other's research. What is the importance of scientists repeating the same experiment using the same steps? It creates further questions to investigate, which creates more accurate results.
Having several trials that produce the same results is more accurate.
When multiple scientists repeat investigations, it allows them to investigate errors.
When scientists get more accurate results, the observations can be compared.
