I'm trying to find a visual method to simply express change in ranked data.
I've done research on exudate levels in wounds assessed to none, light, moderate, heavy or very heavy (ranks 0-4) before and after a dressing has been used.
What I want to do is present the data to show if the exudate level has changed in a meaningful way. Its a small sample size (62 cases).
Is there a method of showing average changes (from before to after) pictorially?
I've found nothing on google or elsewhere on here.
There's no control group so running stats may be innapropriate.
