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 :)
