+NOTE Introduction
+
+00:00:01.360 --> 00:00:03.079
+Welcome everybody. My name is Daniel Molina
+
+00:00:03.080 --> 00:00:05.060
+and I'm going to give this talk
+
+00:00:05.061 --> 00:00:08.063
+"Who needs Excel? Managing your students' qualifications
+
+00:00:08.064 --> 00:00:08.959
+with Org-table".
+
+00:00:08.960 --> 00:00:10.559
+I'm a professor. I work every day.
+
+00:00:10.560 --> 00:00:12.519
+I have to qualify my students.
+
+00:00:12.520 --> 00:00:15.079
+While most would consider normal in this situation,
+
+00:00:15.080 --> 00:00:17.719
+would be to use Excel or LibreOffice
+
+00:00:17.720 --> 00:00:18.599
+for doing that.
+
+00:00:18.600 --> 00:00:21.179
+However, I think that approaching it from Emacs
+
+00:00:21.180 --> 00:00:24.479
+has several interesting advantages.
+
+00:00:24.480 --> 00:00:27.659
+First, I would like to write the qualification
+
+00:00:27.660 --> 00:00:33.599
+next to the justification, next to the student error,
+
+00:00:33.600 --> 00:00:36.639
+and in the Excel format, it's not comfortable to do that.
+
+00:00:36.640 --> 00:00:38.839
+Actually, I always prefer to write in Emacs
+
+00:00:38.840 --> 00:00:42.719
+for many reasons, as many of you.
+
+00:00:42.720 --> 00:00:46.679
+Also, I love text format because I can compare versions
+
+00:00:46.680 --> 00:00:50.279
+using a control version system like Git and easily change.
+
+00:00:50.280 --> 00:00:52.759
+This is very useful for the revision period
+
+00:00:52.760 --> 00:00:55.479
+in which a student visits me
+
+00:00:55.480 --> 00:01:01.039
+and maybe I can change the qualification for any reason.
+
+00:01:01.040 --> 00:01:03.439
+I also can export the results directly to PDF
+
+00:01:03.440 --> 00:01:08.679
+to publish them in my online campus for the student.
+
+00:01:08.680 --> 00:01:11.359
+I have many tools for doing that.
+
+00:01:11.360 --> 00:01:13.199
+I already knew about Org-table formula.
+
+00:01:13.200 --> 00:01:15.199
+I thought it was very cool and useful
+
+00:01:15.200 --> 00:01:16.159
+to use Emacs for that,
+
+00:01:16.160 --> 00:01:19.239
+and I have actually found a package `orgtbl-aggregate`
+
+00:01:19.240 --> 00:01:22.859
+that seemed adequate for doing that.
+
+00:01:22.860 --> 00:01:26.319
+Unfortunately, I didn't see a lot of information
+
+00:01:26.320 --> 00:01:29.159
+about how to do that in a painless way.
+
+00:01:29.160 --> 00:01:31.759
+So, I have to learn, training and testing,
+
+00:01:31.760 --> 00:01:34.999
+and then prepare these tools to solve that problem
+
+00:01:35.000 --> 00:01:36.639
+and to help other teachers.
+
+00:01:36.640 --> 00:01:39.959
+Anyway, it could be used not only for teaching
+
+00:01:39.960 --> 00:01:41.959
+but for more contexts.
+
+NOTE Demonstration
+
+00:01:41.960 --> 00:01:44.799
+Well, let's start.
+
+00:01:44.800 --> 00:01:46.459
+First, I have two sections,
+
+00:01:46.460 --> 00:01:53.399
+the comments and the section of the table, or results.
+
+00:01:53.400 --> 00:01:56.479
+I have... The comment for each student
+
+00:01:56.480 --> 00:01:57.559
+is in a different headline.
+
+00:01:57.560 --> 00:02:05.439
+It's very useful to check with a note.
+
+00:02:05.440 --> 00:02:10.159
+I can go directly using your helm or ivy
+
+00:02:10.160 --> 00:02:12.999
+or consult to go directly to the section.
+
+00:02:13.000 --> 00:02:14.559
+So it's very nice.
+
+00:02:14.560 --> 00:02:22.879
+Then I put the comment, right, completely wrong,
+
+00:02:22.880 --> 00:02:30.599
+it answers other questions.
+
+00:02:30.600 --> 00:02:35.839
+I put other comments here that I could send to the student,
+
+00:02:35.840 --> 00:02:37.480
+you can imagine, and then
+
+00:02:37.481 --> 00:02:40.159
+I can put the qualification, the score for each student.
+
+00:02:40.160 --> 00:02:43.159
+The thing with that is, initially,
+
+00:02:43.160 --> 00:02:46.219
+when I started doing that, I put, I don't know,
+
+00:02:46.220 --> 00:02:50.719
+the exception and a qualification with that.
+
+00:02:50.720 --> 00:02:55.679
+Okay, that's one point, this a three,
+
+00:02:55.680 --> 00:03:06.679
+and use a column total with something like that.
+
+00:03:06.680 --> 00:03:08.319
+Okay, that's nice.
+
+NOTE Range
+
+00:03:08.320 --> 00:03:11.639
+But then, when I started getting more and more parts,
+
+00:03:11.640 --> 00:03:17.081
+I considered it more useful to use,
+
+00:03:17.082 --> 00:03:20.699
+to put for each part,
+
+00:03:20.700 --> 00:03:20.700
+which is the maximum qualification,
+
+00:03:20.300 --> 00:03:22.919
+on the range of the qualification.
+
+00:03:22.920 --> 00:03:25.559
+In that case, I'm going to put,
+
+00:03:25.560 --> 00:03:28.679
+the first one is two scores, the second three points,
+
+00:03:28.680 --> 00:03:34.999
+the third one is one point, and the last one, four points.
+
+00:03:35.000 --> 00:03:37.799
+And instead of putting that in that way,
+
+00:03:37.800 --> 00:03:41.027
+I like to put one is completely right,
+
+00:03:41.028 --> 00:03:47.319
+zero is completely wrong, or maybe some intermediate values for that.
+
+00:03:47.320 --> 00:03:50.999
+Of course, I have to change the qualification,
+
+00:03:51.000 --> 00:03:54.439
+the formula, so it's very simple.
+
+00:03:54.440 --> 00:03:56.479
+I only have to put,
+
+00:03:56.480 --> 00:04:08.299
+multiply the values of the second line with that.
+
+00:04:08.300 --> 00:04:11.899
+So, it's very useful for doing that.
+
+NOTE More qualifications
+
+00:04:11.900 --> 00:04:16.639
+Okay, that's the first part, so I can put the comment,
+
+00:04:16.640 --> 00:04:19.959
+I can go to the section, I can create...
+
+00:04:19.960 --> 00:04:24.919
+I'm going to put more qualifications.
+
+00:04:24.920 --> 00:04:27.639
+Now I'm going to put the table.
+
+00:04:27.640 --> 00:04:30.459
+First I'm going to change, rename the column name,
+
+00:04:30.460 --> 00:04:39.039
+because it's easier when there is only one word.
+
+00:04:39.040 --> 00:04:47.159
+And it's very simple to use. You only have to put
+
+00:04:47.160 --> 00:04:51.439
+the name, aggregate, the name of the table,
+
+00:04:51.440 --> 00:04:54.659
+in that case group A,
+
+00:04:54.660 --> 00:04:57.199
+and in another string, the columns.
+
+00:04:57.200 --> 00:05:03.799
+For instance, name, surname, total.
+
+00:05:03.800 --> 00:05:07.439
+And you can see that you can get a lesson list
+
+00:05:07.440 --> 00:05:09.119
+with all the students,
+
+00:05:09.120 --> 00:05:16.759
+but only with the final score to publish them.
+
+00:05:16.760 --> 00:05:17.679
+Okay?
+
+00:05:17.680 --> 00:05:20.679
+Even you can update the name of the column,
+
+00:05:20.680 --> 00:05:21.800
+not in the original table,
+
+00:05:21.801 --> 00:05:29.559
+but in the lesson table using that format.
+
+00:05:29.560 --> 00:05:32.099
+Okay?
+
+00:05:32.100 --> 00:05:34.239
+That is a good option.
+
+NOTE Subsets
+
+00:05:34.240 --> 00:05:38.499
+Now we are going to see how can we use that
+
+00:05:38.500 --> 00:05:44.359
+to make a subset of the students.
+
+00:05:44.360 --> 00:05:47.839
+For instance, imagine, this is me,
+
+00:05:47.840 --> 00:05:54.799
+I'm going to put the bad, I change, now I can update,
+
+00:05:54.800 --> 00:06:02.759
+you can see this, but also I'm going to put a list
+
+00:06:02.760 --> 00:06:10.960
+with the students that have failed the exam.
+
+00:06:10.961 --> 00:06:21.259
+It's simple, because this package has the option `:cond`.
+
+00:06:21.260 --> 00:06:26.199
+I'm going to put first to see it better,
+
+00:06:26.200 --> 00:06:28.599
+I'm going to put a condition
+
+00:06:28.600 --> 00:06:37.519
+in which we aggregate less than a half, 5,
+
+00:06:37.520 --> 00:06:44.179
+and I have to use a `string-to-number` total.
+
+00:06:44.180 --> 00:06:47.259
+In that way, I can see that this is the student
+
+00:06:47.260 --> 00:06:48.839
+that has failed the exam,
+
+00:06:48.840 --> 00:06:54.079
+I could use that to make another table,
+
+00:06:54.080 --> 00:07:08.299
+this is the people that passed the exam.
+
+NOTE Sorting
+
+00:07:08.300 --> 00:07:10.980
+Another interesting feature is that
+
+00:07:10.981 --> 00:07:15.620
+I can... the lesson table can be sorted automatically.
+
+00:07:15.621 --> 00:07:20.100
+It's simple. You only have to put this symbol (`^`),
+
+00:07:20.101 --> 00:07:23.360
+and you can put next to the column you want
+
+00:07:23.361 --> 00:07:26.999
+to use for the sort, and then you can put
+
+00:07:27.000 --> 00:07:30.679
+`a` if you want to sort alphabetically,
+
+00:07:30.680 --> 00:07:33.879
+in uppercase if you want to reverse the sort,
+
+00:07:33.880 --> 00:07:38.919
+and `n` if you want to sort numerically.
+
+00:07:38.920 --> 00:07:40.759
+For instance, I can put that
+
+00:07:40.760 --> 00:07:43.959
+from the lesser score to the best score,
+
+00:07:43.960 --> 00:07:46.639
+or here from the best score to the lesser score.
+
+00:07:46.640 --> 00:07:48.960
+And this sort is completely independent
+
+00:07:48.961 --> 00:07:51.640
+to the sort of the original table.
+
+NOTE New table
+
+00:07:51.641 --> 00:07:54.520
+Now I'm going to do another different thing,
+
+00:07:54.521 --> 00:08:02.799
+we are going to put a new table,
+
+00:08:02.800 --> 00:08:07.559
+I'm going to put a new table
+
+00:08:07.560 --> 00:08:09.639
+in which I'm going to put
+
+00:08:09.640 --> 00:08:14.319
+the number of passed students, failed students
+
+00:08:14.320 --> 00:08:16.519
+and the ratio of students. It's simple.
+
+00:08:16.520 --> 00:08:26.559
+I'm going to put the pass, in that case, as column,
+
+00:08:26.560 --> 00:08:32.919
+I can put the count, of course, I can put the count,
+
+00:08:32.920 --> 00:08:35.799
+the number of students
+
+00:08:35.800 --> 00:08:42.079
+that have passed, so I'm going to put in that way, ok?
+
+00:08:42.080 --> 00:08:58.479
+I'm going to put pass, count, failed, ratio.
+
+00:08:58.480 --> 00:08:59.739
+You can see, ok?
+
+00:08:59.740 --> 00:09:01.859
+But this only the count,
+
+00:09:01.860 --> 00:09:04.519
+you are going to put the number wrong.
+
+00:09:04.520 --> 00:09:08.359
+So, it's true, but you can actually put formula here.
+
+00:09:08.360 --> 00:09:10.079
+For instance, you can say,
+
+00:09:10.080 --> 00:09:12.399
+I know that I have 3 students,
+
+00:09:12.400 --> 00:09:18.799
+so the number of failed is 3 minus the passed student.
+
+00:09:18.800 --> 00:09:24.959
+And also, I can put the formula, is the people,
+
+00:09:24.960 --> 00:09:27.719
+the students that passed,
+
+00:09:27.720 --> 00:09:36.079
+divide into the number total of students, ok?
+
+00:09:36.080 --> 00:09:41.379
+Let's go to put that in that way,
+
+00:09:41.380 --> 00:09:44.399
+is the people that passed, it is better in that way,
+
+00:09:44.400 --> 00:09:48.359
+and also I can put directly the number of,
+
+00:09:48.360 --> 00:09:50.919
+the ratio of students.
+
+00:09:50.920 --> 00:09:55.739
+So, in that way, I can have a table
+
+00:09:55.740 --> 00:09:57.519
+with the students that passed,
+
+00:09:57.520 --> 00:09:58.559
+the students that failed
+
+00:09:58.560 --> 00:10:01.279
+and the ratio of people that passed.
+
+NOTE Statistics
+
+00:10:01.280 --> 00:10:04.819
+Sometimes this type of qualification will be useful for me,
+
+00:10:04.820 --> 00:10:08.079
+to see how much has been the sound,
+
+00:10:08.080 --> 00:10:12.239
+how much good has been the exercise.
+
+00:10:12.240 --> 00:10:14.879
+Now, I'm going to put a new table.
+
+00:10:14.880 --> 00:10:22.421
+This new table is going to go some statistics,
+
+00:10:22.422 --> 00:10:32.379
+`statistics_score`, `begin: aggregate :table "final"`.
+
+00:10:32.380 --> 00:10:43.919
+In this case, I'm going to use not the original table,
+
+00:10:43.920 --> 00:10:54.019
+but a final, I'm going to put `final_group`,
+
+00:10:54.020 --> 00:11:01.399
+`final_p1`, `final_p2`, ok?
+
+00:11:01.400 --> 00:11:06.119
+And as `:cols`, I'm going to put directly
+
+00:11:06.120 --> 00:11:13.579
+how many results I have, I put number,
+
+00:11:13.580 --> 00:11:19.199
+I'm going to put also the mean.
+
+00:11:19.200 --> 00:11:21.400
+You can see that mean total is not working
+
+00:11:21.401 --> 00:11:24.519
+because I'm using this table and I renamed,
+
+00:11:24.520 --> 00:11:26.079
+the column name was renamed,
+
+00:11:26.080 --> 00:11:36.679
+so it's `mean(Score)`, mean,
+
+00:11:36.680 --> 00:12:05.919
+and then the score. You can obtain `stdiv` -- `sdev`,
+
+00:12:05.920 --> 00:12:08.959
+sorry, there was an error about that,
+
+00:12:08.960 --> 00:12:12.639
+and two decimal,
+
+00:12:12.640 --> 00:12:17.799
+and that is another interesting score.
+
+NOTE Combining
+
+00:12:17.800 --> 00:12:23.239
+Now, I'm going to finish showing how we can use.
+
+00:12:23.240 --> 00:12:25.839
+To finish it, we are going to see
+
+00:12:25.840 --> 00:12:28.299
+how we can combine several tables
+
+00:12:28.300 --> 00:12:32.479
+or even an aggregated table in a new table.
+
+00:12:32.480 --> 00:12:36.259
+For instance, you can have a table for the practice 1,
+
+00:12:36.260 --> 00:12:38.199
+you can have a table for the practice 2,
+
+00:12:38.200 --> 00:12:40.359
+so I'm going to do that.
+
+00:12:40.360 --> 00:12:48.180
+I'm going to move this table. You can copy or remove,
+
+00:12:48.181 --> 00:12:49.759
+doesn't matter the order,
+
+00:12:49.760 --> 00:12:59.519
+I'm going to put this to identify the result of practice 2,
+
+00:12:59.520 --> 00:13:03.321
+Org create an ID (`org-id-get-create`),
+
+00:13:03.322 --> 00:13:07.479
+then we have a previous result,
+
+00:13:07.480 --> 00:13:10.199
+and I have a final table.
+
+00:13:10.200 --> 00:13:11.839
+The final table could be complicated,
+
+00:13:11.840 --> 00:13:17.439
+but it's not so much complicated, it's only that,
+
+00:13:17.440 --> 00:13:21.959
+I'm going to put something that the formula wants.
+
+00:13:21.960 --> 00:13:26.588
+The formula is to make
+
+00:13:26.589 --> 00:13:34.400
+an `org-lookup-first` of the second name,
+
+00:13:34.401 --> 00:13:41.540
+considering that it's unique,
+
+00:13:41.541 --> 00:13:53.439
+`remote` of the surname,
+
+00:13:53.440 --> 00:14:05.559
+and let's say another `remote` of the `$3` element,
+
+00:14:05.560 --> 00:14:15.119
+ok, that's an error because I don't put yet the ID,
+
+00:14:15.120 --> 00:14:19.759
+so I'm going to copy -- mark and copy --
+
+00:14:19.760 --> 00:14:28.519
+and paste the unique ID generated,
+
+00:14:28.520 --> 00:14:38.519
+I'm going to put that... I think there is missing one.
+
+00:14:38.520 --> 00:14:43.399
+Finally. Okay, that's right.
+
+00:14:43.400 --> 00:14:49.579
+So imagine that I change something here, for instance,
+
+00:14:49.580 --> 00:14:56.700
+I put... I change that,
+
+00:14:56.701 --> 00:15:02.199
+actually, this is changed also, and this is changed.
+
+00:15:02.200 --> 00:15:08.599
+This is a good way to divide the classification
+
+00:15:08.600 --> 00:15:10.200
+in several files, one for the practice 1,
+
+00:15:10.201 --> 00:15:15.039
+one for the practice 2, and one final practice
+
+00:15:15.040 --> 00:15:27.639
+that I can finally export in a final table.
+
+00:15:27.640 --> 00:15:31.119
+Of course you can make it a lot more pretty,
+
+00:15:31.120 --> 00:15:33.359
+but this is all I want to show you.
+
+00:15:33.360 --> 00:15:34.799
+I hope with this talk
+
+00:15:34.800 --> 00:15:37.679
+you have learned a lot more about Org formula,
+
+00:15:37.680 --> 00:15:39.688
+[orgtbl-aggregate] package,
+
+00:15:39.689 --> 00:15:42.279
+and how you can use all this techniques
+
+00:15:42.280 --> 00:15:45.599
+to improve your qualification of a student,
+
+00:15:45.600 --> 00:15:50.480
+or for whatever you want.
