The study is to find out if the analysis of the data supports a smoking ban or not. I have conducted a Mann Whitney, and N-Par test and discovered that the data is skewed. I need to explain what the results mean in a discussion section, and am unsure because the data is a little random. Can you help?

column a = id of bar/pub
column b = levels of particles in bar.
column c = levels of uvpm (a measure of amount of tobacco smoke in the air) in the pubs/bars.

column d = levels of nicotine in pubs/bars.
column e = ventilation system (yes-fan ect.) (no= natural ventilation).
column f = smoking/non smoking.
1. = smoking area
2. = non-smoking area.

Smoking and non-smoking pubs.

Here is a brief summary to clarify the difference between the smoking and non-smoking pubs.

o The spreadsheet presents data on levels of pollutants in pubs/bars.
o The first 57 pubs/bars are smoking throughout.
o The rest of the pubs/bars are classed as "non-smoking". This means that, minimally, a non-smoking room is provided. Only two of them are non smoking throughout. Unfortunately, the researchers have not identified which two! In the majority of cases (pubs/bars with a non-smoking area), measurement of the pollutants were taken in the non-smoking area.

I hope this clears things up!
