A Researcher Conducts a Mixed Methods Study on Exercise as a Modality

A researcher conducts a mixed methods study on exercise as a modality of controlling hyperglycemia. The study has both quantitative results, describing the amount that glucose falls with various amounts of exercise, and qualitative results, describing participants' mood and sense of well-being with different kinds of exercise. The researcher decides to publish an article based on the quantitative findings immediately but wait to publish the qualitative results later. What are the reasons that this would not be an instance of researcher misconduct?

A) The data from the quantitative part of the study are reported completely and honestly.
B) The journal does not accept qualitative research.
C) Both "arms" of the study are free-standing: reporting only the quantitative results does not misrepresent the findings.
D) Nobody will know that a qualitative study was performed.
E) No denial of the full scope of data collection is made.
