Define Questions for Investigation

  • Initial Question

Is there a strong relationship between the number of workplace injuries and the type of industry?
Number of injuries by major industries.jpg
I have constructed a bar chart to show the relationship between major industry and the number of injuries in 2014. From the chart, it indicates that construction industry has the least number of workplace injuries which is out of my expectation. Therefore, I decide to break down the major industry. The number of injuries by sub industries .jpg
The chart is created by building hierarchies which clarifies my doubt regarding the previous chart as there are many sub industries under manufacturing and others industries leading to the high number of workplace injuries. After breaking down the major industries, construction is still the most dangerous industry in terms of the number of workplace injuries followed by metalworking under manufacturing and accommodation & food services under others (excluding others-others).
