To know more about the situation of workplace injuries and better deal with it, we need to know the overall trend of the number of injuries and injuries situation in different groups according to different categorizations. Thus, the government can make more specific policies to help employees.

Analytical & Investigation Questions

1. What is the overall trend of number of injuries through the year? 2. What is the overall trend of number of injuries in each day of the week through the year? 3. What is the injuries situation in different occupation? 4. Does the months worked matters? 5. What is the frequency of different causes of injuries?

Data Preparation

1. Data Selection From all the 48 variables, I choose 11 of them. Accident Day Accident Weekday Accident Month Major Industry Sub Industry Body Pars Injured Nature of Injury Accident Type level 2 Category Cause Occupation

       Months worked

2. Check the distribution of the fields To check the categorized data and numerical data and see whether they are valid. For categorized data, I need to know whether the categorizations are typed correct. For numerical data, I need to see whether the distribution make sense.

3. Lowercase Formatting (Occupation) I noticed that the format of Occupation is not consistent which will make it troublesome when using this field. So I used JMP Pro to lowercase the data.
