Revisiting: What to include when your question involves arithmetic

Revisiting: What to include when your question involves arithmetic — setting out what I have, and where I think it stops being reliable.

Counting it rather than describing it, because the count is the part that can be argued with.

13 instances over 18 weeks, recorded the same way each time, 2 of them different enough from the rest that I have set them aside and said so.

That is the whole dataset. The question in the title is what it does and does not support.

This follows post #4 rather than contradicting it.

Units. Everything needs units. This is why we ask every single time. I have seen the same arithmetic done three different ways depending on whether the person was thinking mg/mL or mg/dose or something else entirely. Stating the units makes that impossible.

Not disagreeing with anyone above, just adding the bit I keep having to look up.

Post #12 is the version of this I will quote in future. One addition.

A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the identifiers before you post either.

The specific question in the title is more useful than you might think. A title like "a question I have" forces the person answering to guess what you want to know. A title with the actual question gets you an answer in two hours instead of two days.

I would hold that lightly until someone with a larger sample weighs in.

Post the arithmetic you already did. Half the questions here are answered by someone spotting which line of your working is wrong, and that is impossible if you only give the answer you got.

The mechanism is plausible, which is not the same as established.
