Theme of Interest and Motivation
This Analysis aims to find out overall impressions of different user segments on Wikipedia and their use behavior according to high dimensional survey question answers. Then propose recommendations for Wikipedia's future development. In this analysis, we'll mainly answer the following questions：
- Numbered list item Segmentations of Wiki users.
- Numbered list item Different impressions and use behaviors of different segments.
- Numbered list item Relationships among user impressions, user behaviors, and external environments.
Data Preparation
Transfer Data Type
| Variables | Original Data Type | Transferred Data Type | Reason |
|---|---|---|---|
| Gender | Numeric | Categorical | According to dataset dictionary, gender is meaningless while using numeric value to do analysis. |
| PhD | Numeric | Categorical | According to dataset dictionary, PhD is meaningless while using numeric value to do analysis. |
| University | Numeric | Categorical | According to dataset dictionary, University is meaningless while using numeric value to do analysis. |
| YearsExp | Categorical | Numeric | Years of experience should be continuous data, so that we can firstly bin them into several groups, then use groups to classify them. |
Bin Numeric Data
| Variables | Original | Transferred Variables | Formula |
|---|---|---|---|
| Age |  |
Age(bin) | If(:AGE <= 30,"20~30",If(:AGE <= 40,"30~40",If(:AGE <= 50,"40~50",If(:AGE <= 60,"50~60","60~70")))) |
| YearsExp |  |
YearsExp(bin) | If( :YEARSEXP <= 10,"0~10",If( :YEARSEXP <= 20,"10~20",If( :YEARSEXP <= 30,"20~30","more than 30"))) |
Group Categorical Data
Transform all survey question answers with 1-5 scores to “High, Mid, Low” degree.
| Scores | Degree |
|---|---|
| 1 | Low |
| 2 | Low |
| 3 | Mid |
| 4 | High |
| 5 | High |
