It makes sense to separate the results of an experiment from the scientific conclusion of a research project because

a. the data were collected not as an end in and of themselves but to help evaluate a hypothesis.

b. the scientific conclusion should to refer to what ought to have been collected in the way of data, not the actual data themselves.

c. the dictionary defines a scientific conclusion as a proven result, and the results of an experiment are rarely completely certain.

d. it is good to keep all the experimental items, the design of the experiment, the methods used, the expected results and the actual data collected, in one single category.
