jmp - Process behind how jmp calculates quartiles
I am new to jmp. I have been using Analyze - Distribution to get the quartiles for a quantitative variable.But when I went to double check jmp's process, I was confused.I typed into jmp:9 32 48 52 57 59 60 64 65 70jmp tells me that Q1 is 44, but finding Q1 by hand and using my TI-84 gives me 48. Also, jmp tells me Q3 is 64.25 when by hand it is 64.Can someone tell me how jmp is calculating the q...
