Dear S-PLUS users,
Assume I have the following range:
1 2 3 4 5 6
Next I calculated the 1st Quartile, the median and the 3rd Quartile in
both, S-PLUS and SPSS:
1st Quartile : S-PLUS: 2.25 and SPSS: 1.75
median : S-PLUS: 3.5 and SPSS: 3.5
3rd Quartile: S-PLUS: 4.75 and SPSS: 5.25
Or for this range:
1 2 3 4 5 6 7 8
the results are:
1st Quartile : S-PLUS: 2.75 and SPSS: 2.25
median : S-PLUS: 4.5 and SPSS: 4.5
3rd Quartile: S-PLUS: 6.25 and SPSS: 6.75
So S-PLUS and SPSS give different results. Which results are correct? And how
can these results be explained?
