Abstract

Workplace Safety and Health (WSH) includes legal requirements, certification and registration, monitoring and surveillance, accident reporting and work injury compensation. We understand that certain types of work may have higher chance of getting injured, and some injures are due to bad management and overtime. So based on data given by Workplace Safety and Health(WSH), we want to explore the patterns of work-related injuries.

Data Visualisation System Design Process

1. Identify a theme of interest
Safety has always been a great concern to Workplace Safety and Health (WSH) and it has always been trying to reduce work-related injury. A work-related accident is any unintended event that occurs in the course of work (excluding domestic work) that leads to an injury or condition. Based on injury data given by Workplace Safety and Health (WSH) We try to identify patterns of injuries types, victims' characteristics, and injury time.
2. Define questions for investigation
Are there patterns in accident occurring time?
What are the industries/occupation that accidents occur frequently?
Are there and what are the patterns of injuries types?
Are there and what are the patterns of victims?
3. Find appropriate data attributes
Among all only 26 columns are chosen, and they are shown in the graph.

Then we realize for the occupation column, there are duplicates, and the only difference is uppercase and lowercase. As graph shown 'cook' is the same as 'COOK'.

So I used JMP Pro lowercase function lowercase the occupation column as the graph shown.

And the missing values are insiginificant.

Analysis

Q1. Is there a relationship between the experience of employees and workplace injury?

From the graph above, we noticed that
Q2. Are there patterns of injury time

Q3. Are there Patterns of injury types
