Mean, Median and Mode from Grouped FrequenciesAnother new stats page: Mean, Median and Mode from Grouped Frequencies "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20131019 11:01:26
Re: Mean, Median and Mode from Grouped FrequenciesHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20131019 21:28:49
Re: Mean, Median and Mode from Grouped Frequencieshi MathsIsFun, It doesn't make much difference and it's only an estimate anyway, but, for example, with the baby carrots example I get 172.0, compared with your 171.7. I drew a cumulative frequency graph and found the median from that as 172. I've done some 'googling' and both formulas came up. eg. http://www.thestudentroom.co.uk/showthread.php?t=908222 http://math.stackexchange.com/questions … stribution Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #4 20131022 15:17:14
Re: Mean, Median and Mode from Grouped FrequenciesVery interesting, thanks! "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman
