In scientific writing, a hypothesis is a testable prediction or explanation based on prior knowledge, while a conclusion summarizes the findings of an experiment or study. The hypothesis acts as a starting point for investigation, guiding the research process and establishing what to investigate. After collecting and analyzing data, the conclusion reflects whether the results supported or disproved the hypothesis, helping to inform future research directions. While the hypothesis is an initial idea pending verification, the conclusion provides insight into the outcome of the scientific inquiry and its implications.
