Revision as of 22:03, 5 October 2016
According to a survey of more than 14,000 international students in Australia and the UK, 77% of students listed both university and subject rankings as “very important” when deciding a place to study. As such, given the importance of these rankings in decision-making, we were inclined to provide an interactive outlet to aid students in their decision-making process.
In addition, most rankings systems online are in a tabular format. This makes it difficult for anyone to truly visualize the information being displayed and how various factors interact with each other. Thus, our team aims to create a dynamic visual that not only provides interactivity between factors but also reveal hidden patterns of associations that tabular formats might miss out.
Who can use our visual?
- Pre-university selection for students
- University students planning to go for exchange
What can be derived from our visual?
- Effect of factors on ranking of university
- Location of universities
- Trends of school make-up
- Overall ranking of universities
- Multi-Comparisons between universities based on factors
Our project will be based on the Times Higher Education World University Rankings. (Extracted from: https://www.kaggle.com/mylesoneill/world-university-rankings)
Our project will analyze the following attributes,
| Label | Description |
|---|---|
| world_rank | world rank for the university. Contains rank ranges and equal ranks (eg. =94 and 201-250) |
| university_name | name of university |
| country | country of each university |
| teaching | university score for teaching (the learning environment) |
| international | university score international outlook (staff, students, research) |
| research | university score for research (volume, income and reputation |
| citations | university score for citations (research influence) |
| income | university score for industry income (knowledge transfer) |
| total_score | total score for university, used to determine rank |
| num_students | number of students at the university |
| student_staff_ratio | Number of students divided by number of staff |
| international_students | Percentage of students who are international |
| female_male_ratio | Female student to Male student ratio |
| year | year of the ranking (2011 to 2016 included) |
Where performance indicators are grouped into five areas:
| Label | Description |
|---|---|
| world_rank | world rank for the university. Contains rank ranges and equal ranks (eg. =94 and 201-250) |
| university_name | name of university |
| world_rank | world rank for the university. Contains rank ranges and equal ranks (eg. =94 and 201-250) |
| university_name | name of university |
| university_name | name of university |
- Teaching (the learning environment)
- Research (volume, income and reputation)
- Citations (Research influence)
- International outlook (Staff, students and research)
- Industry Income (Knowledge transfer)
Note: Universities were excluded from the rankings if (i) they do not teach undergraduates or (ii) research output amounted to fewer than 200 articles per year over a five year period (2010 to 2014).
Breakdown of performance indicators
Source: https://www.timeshighereducation.com/news/ranking-methodology-2016
After referencing to multiple previous works that display university rankings, we decided to focus only on The Times Higher Education World University Rankings The rationale is that the dataset provided is robust enough to tell a good story, and that we cannot feasibly combine data from multiple sources. Our other choices and sources which we eliminated were:
1) World University Rankings 2015-2016
We started with the web app provided by the official Times Higher Education website itself and we realised it provided good filtering systems but the app does not visualize the data. This reference helps us to know which filtering categories are important
2) Caleydo LineUp: Visual Analysis of Multi-Attribute Rankings
Next we wanted to value add to an existing visualisation for university rankings and its factors. This one uses bar chart and LineUp so even though they are informative, we wanted to have something else to show in addition to what the visuals currently display.
3) Which universities do good science
This work from Kaggle itself shows us the benchmark and inspiration for which variables are used to compare and gain insights from. The work features mostly scatterplots and even a correlogram. We have then decided to adopt a more multidimensional approach to visualizing the data and decided with glyphs and ternary plots.
