What should be avoided in the results section of a scientific report?

The correct choice indicates that the presentation of raw data should be avoided in the results section of a scientific report. This section is intended to summarize and present analyzed data clearly and concisely, focusing on the main findings that result from the study's statistical analyses.

Presenting raw data can overwhelm readers with unnecessary detail and complexity, making it difficult to identify significant findings. Instead, it's more beneficial to distill the data into comprehensible formats, such as tables or graphs, that highlight key results and trends while also facilitating interpretation.

The other options contribute positively to the results section. Clear visual displays of data (like graphs and charts) help convey findings effectively. A detailed summary of the statistical tests used aids in understanding the methods applied and supports the credibility of the results. Discussing findings in relation to background theories typically belongs to the discussion section, not the results section, as it involves interpretation and synthesis rather than straightforward reporting of findings.
