Time savings and chemical savings are separate outcomes. A quicker clean may still use more product.

Two groups can share the same average while differing greatly in consistency. A measure of spread helps reveal that difference.

A ranking can imply a meaningful separation even when the measured difference is small relative to variability or uncertainty.

A before-and-after mass comparison needs the same assembly at both weighings. Removing a cap or changing an applicator arrangement can distort the difference.

Data exclusions can be legitimate, but selective removal after seeing unfavourable results undermines the comparison.

Six months of calendar exposure can represent very different use patterns. Record relevant use alongside dates.

A truncated or hidden scale can exaggerate a small difference. Readers need enough context to understand the magnitude.

Testing many outcomes creates opportunities to select whichever result looks best. A primary decision criterion keeps the evaluation focused.

A single precise estimate can hide uncertain surface area, preparation time or material consumption. A documented range makes those assumptions visible.

Rework consumes more than replacement material. It may also occupy a bay and interrupt other accepted work.

Enquiries indicate interest but are not equivalent to confirmed purchases. Mixing them can inflate the stock plan.

A sampling plan needs a clear population. Mixing unrelated production or packaging groups can make the sample difficult to interpret.
