Univariate Analysis
Appointment Duration
We performed univariate analysis on appointment duration to find out the current distribution and summary statistics and obtained the following results:
- Mean duration: 1:22
- Median duration: 1:12
- Standard deviation: 0:47
- Non-parametric distribution
Bivariate Analysis
We performed bivariate analysis on each independent variable to find out their individual effect on appointment duration and obtained the following main findings:
Appointment Clinic
The median duration differs from clinic to clinic. The longer average appointment duration includes SNEC (Singapore National Eye Center), NUH (National University Hospital), and NCC (National Cancer Centre). The shorter durations mainly come from neighborhood polyclinics, such as Geylang polyclinic, BMP (Bukit Merah Polyclinic), and CWC (Community Wellness Centre).
Appointment Purpose
From the distribution analysis, we can see that Ophthalmologist takes the longest duration while Tests takes the shortest duration.
Escort
Analyzing the appointment durations when there is Next-of-kin accompaniment vs Family (more than 1 NOK) accompaniment vs Medical escort accompaniment, we see a difference in median appointment durations. We conducted a non-parametric paired significance test and conclude that with the accompaniment of a medical escort, the median appointment duration is lower than the accompaniment of NOK or family.
Multivariate Regression
Stepwise Regression
As we have many independent variables and sub-variables, we will perform a stepwise multiple linear regression to select the relevant variables. The results also reveal how the partition splits are done.
