Dear student,

starting this week, Tutorial 1 will take place online on TEAMS and the time will move to Wednesdays 14:15-15:45. It is open to everybody who prefers this mode and/or time slot and can be joined on TEAMS with the following link:

https://teams.microsoft.com/l/meetup-join/19%3ameeting_ZGUzYzNlMDEtZTMzOC00NWIzLWIyZDctZmY1NjQ4Y2Q5MTBl%40thread.v2/0?context=%7b%22Tid%22%3a%2267610027-1ac3-49b6-8641-ccd83ce1b01f%22%2c%22Oid%22%3a%229934c552-fdfd-4a09-bea0-00dc0df2a20b%22%7d

If you are in Tutorial group 1 and would prefer to keep the current time and attend in person, please feel free to join Tutorial group 2 regularly.

 

Furthermore, an annonymous feedback post has reached us that I would like to address here:

question: The post indicated that the degree of detail necessary and wanted in questions that ask for the reporting of effects was unclear. Especially, question 5 b on the sample exam seemed to ask just for a simple decision, while the sample solution featured relevant statistics etc.

answer: „Report“ has a special meaning and always includes stating the relevant statistic and significance. We are usually also interested in direction and magnitude of an effect, if this information is available from the model output (not the case for ANOVA and chisquare output). When we ask to report an effect, we don’t want you to explain general concepts like what a coefficient is or what significant means, but to give your scientific conclusion as you would do in a scientific paper. You will usually not lose points in the exam, if you do explain the concepts behind it though. What we expect is that you concentrate on the important information, i.e. reporting on effects does not include reporting on model fit and if we ask to report in the light of a specific research hypothesis, we expect you to be able to select relevant portions of model output.

In general, giving justifications of decisions on the exam is wanted, we will usually also indicate this in the question and this is not ideal in question 5 b on the sample exam, "Justify your answer" should have been added.

 

Best wishes,

Emilia

Dear student,

due to sickness, three tutorials are cancelled this week, but we try to give each of you the chance to attend, so:

tutorials 1 & 2 will meet together at the usual time (8:15) in room SR016 with Maike Kalms

tutorial 3 unfortunately has to be cancelled. Please feel free to attend any other tutorial slot this week.

tutorials 4 & 5 will meet together at 10:15 in room SR 014 with Aarushi Singhal

tutorial 6 will be unaffected

In addition, we had some feedback with the request to shift the weekly deadline for exercise sheets to Tuesdays. Unfortunately, this is not possible, as the tutors need enough time to look through submissions before the tutorial and to grade them in a timely manner. For next week (sheet7, not released yet), however, we have shifted the deadline to after Christmas (December 28) to give you some more time.

As a last remark, there is another obligatory datacamp course coming up, which is due on January, 8.

Best wishes,

Emilia Ellsiepen

Dear student,

the date for the re-sit exam has been fixed to March 12, 9:00. The main exam will take place on February 20, 14:00. Both exams will last 90 minutes.

There will be some practise exam questions for the content covered so far available on cms before the Christmas break, which will be discussed in the first tutorial session in January. You do not need to hand in your solutions, it is just for you to practise and prepare for the exam.

With regard to the regular exercise sheets, please be reminded that you need to provide an answer for each subquestion. Not answering subquestions will lead to a fail on the entire exercise sheet.

Best wishes,

Emilia Ellsiepen

Dear student,

if you are not yet part of an assignment group, please create one for yourself, if you want to submit exercise sheets. We will then combine groups with less than 3 members.

If you have admission to the exam already or if you do not plan to take the course for credit, this does not apply to you.

Best wishes,

Emilia

Dear students,

if you have orgnaizational questions regarding this course, we invite you to post them on the forum instead of asking individual tutors, such that we don't need to answer the same question multiple times.

Also, please use the official contact from the cms page instead of private contact information of your tutor that you happen to have.

Thank you,

Emilia

All students have now been assigned a tutorial slot. Please check, whether you can make the time and get in touch, if you need to change slots.

This year, we offered a "no tutorial" slot, which is meant for students, who are retaking the course and don't have to submit exercise sheets. If you have been assigned to that tutorial (#7), but are taking the course for the first time and for credit, please get in touch! If you are retaking the course, but were still assigned to a tutorial slot other than #7 although you opted for the "no tutorial", also get in touch!

Retakers are welcome to join the tutorials to refresh their memory and get some more practise.

Students registering late, will be distributed to the tutorials as soon as possible for us.

Please be reminded that the first datacamp assignment is due on October 31!
