ABSTRACT
We have the data about Survey of faculty members from one Spanish university on teaching uses of Wikipedia. According to the data, we can get the answers for the series questions about how can Wikipedia help students and what areas are mostly need Wikipedia. in this page, some data visualization methods will be included in order to show the result clearly.Though the analysis, we have some interesting findings:
- In the Arts&Humanities majors, Wikipedia has quite usefulness and professional explanations for some terms.
- In the Law&Politics areas, Wikipedia is hard to give the satisfied answers according to the survey.
Motivation and Problems
Recently, more and more teachers are considering about using Wikipedia as a kind of teaching tool. In addition, many famous Proof will join the Wikipedia edition work. So for most school, teachers maybe no need to waste time on the class knowledge preparation. students can increase their knowledge by viewing the Wikipedia. It is quite useful to search some terms in Wikipedia.
but now, schools and teachers are worried about the professional degree of the Wikipedia, at the same time, Wikipedia can see which aspects it needs to improve according to the survey.
- How majors impact people in Wiki work in students&teachers' usefulness?
- Which aspects Wikipedia needs to improve?
Approach
The data was obtained from https://archive.ics.uci.edu/ml/datasets/wiki4HE
in the last part, the data dictionary is given so every detail can been seen in the last.
The Treemap and histogram are used in this page.
Interactive Data Visualization
Here is the link of my Tableau public: https://public.tableau.com/profile/zhangjinchuan#!/vizhome/assignment2_36/Story
that allow you view the story and explore the result.
Tools Utilized
In this page, these tools are used:
- Tableau 10.0
- JMP Pro
Data Preparation
Data cleanning
After input the Csv file into JMP, we can find some data are lost, in this case, we just exclude them so we can see the result more clearly. we only choose the UOC, so excluded all the UPF data. in addition, we do not need OTHERS and OTHERS POSITION since they give uncompleted information.
Label change
Since the raw data file used number represent the different meanings, so we need to change the label back so that we can read easily in the treemap. by using RECODE function in JMP, we replaced the numbers in the raw data.
Data analysis
After finishing the data preparation, input the data into the Tableau, so that we can do the analysis work.
