Why am I getting a wrong result for quartiles? here is my code:
> cbiomass = c(910, 1058, 929, 1103, 1056, 1022, 1255, 1121, 1111, 1192, > 1074, 1415) > summary(cbiomass) > IQR(cbiomass) The result R gives me is: For the summary > Min. 1st Qu. Median Mean 3rd Qu. Max. 910 1048 1088 1104 1139 1415 For IQR > 91.25 ********* The true Q1 is 1039 and not 1048. Q2 is 1156.5 and not 1139. And the Inter-Quartile Range is 117.5 and not 91.25 How can I get these number right? -- View this message in context: http://n4.nabble.com/Quartiles-and-Inter-Quartile-Range-tp1145817p1145817.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
