Course Statistics
Hello Learning Community,
We had a detailed look at our database and in order to give you a feeling how you performed in comparison to your fellow students, we extracted some information from it.
Many of you already asked for additional information like some demographic information and a more detailed look into the scorings to rank yourself. Since we believe it is more convenient to see a detailed overview of the sum of reached points in graphs, we did not send this information in the announcement but present it on this wiki page with some accompanying thoughts. In the figures, we omitted all learners who did not take part in any of the assignments.
The determination of the top 5, 10 and 20 percent of all learners was done based on the group of "all learners who received the graded Certificate". This group consisted of 2443 learners, which were ordered by their results and then assigned to the respective groups.
The resulting ranking scores are:
TOP 5% > 190 Points
TOP 10% > 186 Points
TOP 20% > 179 Points
Best regards,
The Teaching Team
Score Analysis:
First, perhaps the most anticipated overview: the scorings. The spikes on every second bar, especially in the higher point ranges, may seem strange at first. But given the fact, that most questions were rewarded with 2 points, and only some were scored with 1 point, makes this more reasonable.
If we break down the scores to single assignments, we get the following info:
Assignment Week 1: 4195 submissions, average score 69%
Assignment Week 2: 2915 submissions, average score 75%
Assignment Week 3: 2843 submissions, average score 80%
Assignment Week 4: 2815 submissions, average score 82%
Assignment Week 5: 2647 submissions, average score 81%
Assignment Week 6: 2584 submissions, average score 89%
Final Exam: 2782 submissions, average score 78%
Demographic Analysis:
The following overview was already shown in week2, but for the sake of sake of completeness of all statistics, we present it here again. People from the blue colored countries participated in this course:
Additionally, we now made a statistic about the distribution of students to countries (based on the video requests). The top 3 countries were Germany, India and the US. In comparison to the last iteration, participants were more distributed over the world (in 2012, the share of german participants was > 50%) so we are happy to announce that we became more international.
For the following graph, only students who reached the certificate were taken into account (the set of all students contained too many uncertain entries, i.e. ages above 123 (maximum: 2011) or below 8 (minimum -6). The majority of the participants is between 20 and 50, which was also expected. However, we are happy to say that also quite some learners above 60 took part and enjoyed the feeling of being "back in school".
And, last but not least, a rather simple graph about the gender distribution (distributions are nearly the same when comparing "all students" and just those who gained the certificate). IT still seems to be a male dominated field. This distribution is similar to the one of the first iteration.
