Hi Everyone,
I have a very long list of data-points (+2300) and i know from my
histogram
that there are outliers which are affecting my mean.
I was wondering if anyone on here knows a way i can quickly get R to
calculate and remove data which is 3 standard deviations from the
mean? I am
hoping this will tidy my data and give me a repeatable method of
tidying for
future data collection.
Please if you do post code, make it as user friendly as possible! I
am not a
very good programmer, i can load my data into R and do basic stats
on it
however i havent tried much else....
Thank you in advance for any advice given :)
This plan has no statistical justification. Around here we have
reverence for data. Outliers are often meaningful. Requests to distort
your data should be accompanied by a coherent argument.
