Final answer:
The Materials and Methods section of a research article should include descriptions of substances, techniques, and instruments used in the research but should not include conclusions, claims, or duplicated data tables or graphs.
Step-by-step explanation:
Components that should not be included in a Materials and Methods/Experimental section of a research article include:
- The conclusions that can be made from the data taken in the research project.
- The claims that the author wants to make regarding the research.
- Results figured in tables or graphs that duplicate information already presented elsewhere in the paper.
The Materials and Methods section should focus on the description of substances used, techniques and types of instruments and devices used to conduct the research, and how the data was collected. It should provide enough detail for another researcher to replicate the study but should avoid discussing the results or interpretations of the data, which are covered in other sections of the paper.
