It is important to carefully follow the experimental design to avoid introducing unwanted ___________ that could affect the experimental results.

Controlling extraneous factors so they don’t influence the outcome is essential in experimental design. When other elements vary between groups or conditions, these unwanted factors—extraneous or confounding variables—can masquerade as effects of the factor you’re intentionally testing, leading to misleading conclusions about what actually caused the results. By carefully aligning conditions, randomizing, and standardizing procedures, you limit these variables and keep the observed change attributable to the experimental manipulation.

In this context, the term that fits best is variables, since it refers to any factors that could vary and affect the results. Data to collect or the specific values you test are not the unwanted influences themselves, and p-values are a statistical measure after analysis, not something introduced by the design.
