Quartiles and Inter-Quartile Range
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
