The FINAL step in a scientific investigation is to

A) conduct the study.
B) analyse the data.

The final step in a scientific investigation is to report the findings. This includes sharing the research with others, discussing limitations and potential future research, and making the findings available for peer review and replication. While conducting the study, analyzing the data, and deciding whether or not the hypothesis was supported are all important steps in the scientific method, they are not the final step.
