Ages in RAFAC

Decided to get ChatGPT to do some analysis from this FOI request

Few interesting tid bits

It really annoyed me how They don’t follow a Normal Distribution so I got a table

The cadet Rank distribution is as would be expected

(ChatGPT failed the maths on London wing not me)

Shockingly no outliers for Flt Lt or WO

Basically what this waffle is leading to is why do some areas of the UK have Such high Average ages for Junior Uniformed Ranks? Are these areas struggling to get younger staff, hence the wing average being dragged up?

Any insight or ideas would be great!

(also all the boring Calculation data, and parameters are available, just thought this post was long/boring enough)

Have you referenced against the original data to ensure that 48 year old average for Sgt and 54 for PltOff is correct?

I did, 1WW for the Sgt, N&S for the Plt Off,

although I am dubious of some of the other data I’m checking

Have you determined non-normal distribution from eye or done a statistical test to confirm it? Eg. Shipiro-Wilks would be my go to.

eyeballed it tbh, they mostly have the features of a Normal curve, but its some of the gaps, or Obvious outliers such as the 48 year old sgt average

I’m not a Stats expert, quite honestly it’s my least favourite part of my Maths course

Edit:

hahahaha

no.

based on data i remember Wing sharing many moons ago, staff ages is not a normally distributed data set across all the ranks.

many join in their 20s, mostly ex Cadets directly or soon after Uni or other distractions.
then they stick around for ~10 years, then end up married, with kid(s) which are a priority and so sees people leave. some of those return ~10 years later as their kid shows an interest and so they reengage - or for those without prior CFAV experience is the time they first get involved when their kid shows interest

I have found that graph and none of the lines, be it separated by flavour of commitment or overall shows “normal” distribution based on age - this date is almost 10 years old so not current, and won’t take into account and post Covid19 effect but offers some real numbers…
