Why the scientific method may not follow the exact same steps each time through the process

The scientific method may not follow the exact same steps each time because experiments are different. Some may have many more steps to follow to reach the conclusion, while others may take less time and have less steps. For example, some experiments may require a chart or graph of the results to be made, while others do not need that to display the results.
