You are free to use these assignments in self study and other courses (CC-BY-NC 4.0), but please do not publish complete answers online.
There are 9 weekly assignments (two of them have two weeks to submit). Assignments are linked from the schedule and can also be found from git repo assignments folder. The deadline days for the assignments are given in the course schedule.
NOTE: The assignment instructions can be updated during the course, and individual assignments are not guaranteed to be up to date until Monday 8am of the hand-in period of the corresponding assignment week (See the deadlines below, e.g. the first assignment is not guaranteed to be up to date until 4.9. at 8am).
Report all results in a single, anonymous *.pdf -file. Do not include your name, student id, or other information that can identify you (Peergrade knows who submitted what). You can choose the file name freely. Submit the report it in peergrade. Submitting empty or almost empty pdf files is not allowed (this will be handled as a violation of academic integrity as it is harming other students). Include also any source code to the report (either in appendix or embedded in the answer). By anonymity it is meant that the report should not contain your name or student number. In addition to the correctness of the answers, the overall quality and clearness of the report is also evaluated.
The assignments are mostly solved using computer (R or Python). Related demos for each assignment are available in the course web pages (links in Materials section). See TA sessions for getting help.
Overall recommendation for many students is to include more text explanations as writing that text is an active way of learning, and also it’s easier to see if you have understood the concepts correctly. If you make minimal reports, you will also get minimal feedback and you learn less. The main purpose of the course is to learn, and learning is more effective if you do it in active and interactive way.
For those who are self studying or who miss several assignment hand-ins, there is a possibility to hand in all assignments once in period III (no need to ask permission for this as this is automatically granted for everyone). We still strongly recommend students taking the course to follow the weekly submission deadlines to more evenly spread the work for them and the reviewers during the course.

Peergrading is called giving feedback in peergrade.io. Giving feedback is good term as it is not meant to be just grading wrong vs. correct answers. Please provide also feedback on the presentation. Part of the course is practicing making data analysis reports. By providing feedback on the report presentation other students can learn what they can improve or what they already did well. You should be able to provide constructive or positive feedback for all non-empty reports, even if there is nothing to say about the technical correctness of the answers. If you all provide more feedback, you will all learn more about good data analysis reports. Be kind.
Points are given from both submitting an assignment and giving feedback. Submission performance gives 80% and feedback performance 20% of the total score. Only those students who returned a given assignment are allowed to give feedback to the answers submitted by others.
You don’t need to get 100% score from the submission or feedback to get grade 5. Thus, one should not worry about getting a 100% score. A critical reviewer will also affect other students’ grading. In addition, a question can always be flagged for course personnel to check.
We have noticed in previous years that some students return an empty pdf to peergrade to still get points from giving feedback. This is not allowed. If a student returns an empty pdf or it is obvious from the pdf that the student hasn’t done any effort for the assignment, the student is not allowed to give feedback. The course staff will monitor returned assignments, and negative points will be awarded to empty assignments. If any student is reviewing an empty pdf, please contact course staff.
After peer grading is over for an assignment, each submission receives a submission score. This score is between 0% and 100% depending on how well the peers evaluated the submission. This is mostly about the technical correctness and small part about the presentation.
The numerical score for each criteria is normalised to be between 0% and 100%, where 0% is given to the worst, and 100% to the best possible answer. As an example, in a Scale-question with 5 levels, the different answers will count 0%, 25%, 50%, 75%, 100%.
The total submission score is calculated for a submission by averaging the scores from each of the peers. The score from an individual peer evaluating a submission is obtained by averaging over the criteria in the feedback rubric.
Within each assignment, there are two sections Basic requirements and Overall quality of the report. These segments are weighted so that they each provide 7.5% of that assignment’s total score. The remaining 85% is distributed evenly to the rest of the sections. Within each section, the points are distributed evenly among each question.
If a student has flagged some of their received evaluations and a TA has accepted the flag and overruled the original evaluation, then TA’s new evaluation is used for computing the score instead. If a teacher overrules a specific evaluation by one student, that answer is taken to be the correct one for that part of that submission. This means that the evaluations by other students on that part are disregarded in the final score of the submission.
There are 9 assignment rounds in total. Each round has different weighting when computing the total score. The assignment instructions list max points for each assignment as 3, 3, 9, 6, 6, 6, 6, 6, 3. These translate (approximately) to weights 6%, 6%, 19%, 12%, 12%, 12%, 12%, 12%, 6%.
The feedback score depends on the reactions, such that a student’s feedback score on an assignment is an average of the reactions received. If no reactions have been given to the student’s reviews, no feedback score is computed and it will simply show as “-”.
When you provide feedback, you can provide constructive and positive feedback on how to improve presentation or tell what is already very good. If the report is perfect and you can’t come up with anything to improve, you can tell what did you like about the report. By providing that kind of feedback you are more likely to receive higher feedback score. Even
The following are reasons to react positively to feedback:
Be kind when reacting to to the feedback. If you didn’t like the feedback, think first a moment, and then re-consider whether it was just the wording that got you angry and maybe there is something useful in the feedback.
Note that the baseline feedback reaction is “Somewhat useful. Could be more elaborate.” which corresponds to 0.5 points or as Peergrade shows it to 50%. If you receive 100% you have exceeded the expectations.
In addition to the peergrade score, one can get bonus points from course chat activity (e.g. helping other students and reporting typos in the material) and by answering a time usage questionnaire on the course page in MyCourses. Course chat activity and the questionnaire are not included in the maximum assignment score and thus are not required to receive a full 100% score.
Other students’ course chat activity will not affect one’s resulting grade, i.e. there is no need to try to perform in the course chat or to take any part in it at all.
After each assignment, a voluntary anonymous questionnaire is opened on the course page in MyCourses for the peergrading feedback period (Monday 8:00 to Wednesday 23:59).
Remember to be polite when peergrading, giving feedback, and reacting to feedback. Do not spend a lot of time fighting over the grading of one question from one student. If you don’t agree you can submit a flag or in extreme case contact the TAs. Also, keep in mind that in most of the cases, which we’ve seen, the students have been fighting for points which have less than a 1/1000 effect on the final score. Long fight over that is not worth the time and energy. If you get feedback which makes you angry, breath and wait a moment before unleashing your anger back. We ask you to honor the system and be polite to your peers.
You can get help for the assignments by asking in the course chat from other students or in weekly TA sessions by asking TAs. The sessions are voluntary.
