Sample letter grade calculation:
90-100 = A
80-89 = B
70-79 = C
60-69 = D
0-59 = F
I am deeply sorry if this has been addressed before here. I have
searched but could not find any reference.
I am a teacher and have been using org-mode in combination with noweb as
a class manager. I also use moodle and blackboard but I like to keep my
lecture notes and student grades local on my machine. I typically have
the above table for student grades (usually substantially more than
that). I am able to calculate many things like averages, etc., but would
like to have letter grades and "best performing" comments by the
students doing as well.
Starting with letter grades, is there a way I can evaluate the Total
column and assign letter grades as shown above? Thanks

If you sort the resulting table like this: 1) Position cursor on any total value 2) M-x org-table-sort-lines 3) N (for reverse numeric sort) Then update the Rank column with C-u C-u C-c C-c anywhere in the table the rank numbers are recomputed starting from 1 on the first row. I hope your blank lines aren't too important because sorting puts them all at the bottom of the table. Does that do what you want? -Bernt ^ permalink raw reply [flat|nested] 6+ messages in thread

The blank lines do also pose a problem in different approach, one which will make use of vector functions in calc. If you allow for no empty lines and one extra line toward the end of table, this also can do the computation. | | Rank | names | grade 1 | grade 2 | grade 3 | Total | Letter grade | |---+------+------------+---------+---------+---------+-------+--------------| | # | 1 | student 01 | 91.80 | 96.40 | 97.00 | 95.07 | A | | # | 2 | student 03 | 92.00 | 95.14 | 97.00 | 94.71 | A | | # | 3 | student 02 | 88.78 | 89.15 | 98.00 | 91.98 | A | | # | 4 | student 04 | 84.00 | 74.62 | 88.00 | 82.21 | B | |---+------+------------+---------+---------+---------+-------+--------------| #+TBLFM: $2=find(rsort(@I$7..@II $7),$7)::$7=($4+$5+$6)/3;%.2f::$8=if($7<60,F,if($7<70,D,if($7<80,C,if($7<90,B,A)))) > > Does that do what you want? > > -Bernt > > > _______________________________________________ > Emacs-orgmode mailing list > Remember: use `Reply All' to send replies to the list. > Emacs-orgmode@gnu.org > http://lists.gnu.org/mailman/listinfo/emacs-orgmode > [-- Attachment #1.2: Type: text/html, Size: 3914 bytes --] [-- Attachment #2: Type: text/plain, Size: 204 bytes --] _______________________________________________ Emacs-orgmode mailing list Remember: use `Reply All' to send replies to the list.

And this doesn't require that you sort the entries first to get it right - so I like Gabriel's solution better. This way you are free to sort the table anyway you like and the data is still correct. -Bernt ^ permalink raw reply [flat|nested] 6+ messages in thread
