4. Table 1.1 (below) shows the number of job-related injuries for each of the transportation industries for 2016. Review Table 1.1 and respond to the inquiries that follow. Table 1.1 Industry Number of Injuries 9950 5100 6850 7144 4520 Airline Intercity Bus Subway Trucking Railroad #1 for Beh 4a. What are the two variables under study? 4b. Categorize each variable (re: Table 1.1) as qualitative or quantitative. 4c. Identify the level of measurement for each variable (re: Table 1.1). 4d. Which type of chart- Histogram or Pareto- would be most applicable for the data. Explain your response/rationale?Explanation / Answer
4a. The 2 variables under study are:
Type of transportation industry and number of job related injuries.
4b. Here,
The 1st variable, Type of transportation industry is qualitative in nature
And the 2nd variable number of job related injuries is quantitative.
4c. Level of measurement of:
-Type of transportation industry is nominal (lowest level of measurement), since the data points belong to certain number of categories
- Job related injuries is ratio scale (highest level of measurement), numerical in nature with zero absolute value (which is not apt for interval scale, in case there is no job related injuries in a particular industry).
4d. Among Histogram and Pareto, Pareto would be most applicable to the data, since it highlights the highest occurring phenomenon (frequency), in this case, which industry faces largest job related injury cases, hence the most risk.
Histogram would provide an idea on the overall distribution of the data.
