Question

Suppose that you are the Safety Manager for a company, and you have to find out if a new method of safety training is better than the method you are currently using. Explain how you would do this by conducting a between-groups experiment with the workers, who are organized into 10 teams.

You must answer in complete sentences for full marks.

1. State a Hypothesis. (0.5 marks)
2. What would you measure to find out if the new training method is better? (1 mark) Identify a limitation of what you measure or how you measure it. (1 mark)
3. State the Independent Variable and the Dependent Variable. (0.5 marks)
4. Who would be in the Experimental Group and who would be in the Control Group? (0.5 marks) How should these groups be assigned to avoid any bias? (1 mark)
5. What would you do with the data you collect to test your hypothesis? (0.5 marks)

My answers:

A: State a Hypothesis.
Using new method where there will be no injuries and that health and safety are guaranteed. There will
be improvement in new method
B: What would you measure to find out if the new training method is better? Identify a limitation of
what you measure or how you measure it?
- Measure the reactive monitoring of the new training, and how effective the new one from that of
the old one.
- You can get real and actual results only by applying it in real time, so time factor is the limitation.
Also, it may not be accurate when testing the hypothesis.
C: State the Independent Variable and the Dependent Variable.
The independent variable is the time spent on the training program.
The dependent variable is the actual participation of group used.
D: Who would be in the Experimental Group and who would be in the Control Group? How should
these groups be assigned to avoid any bias?
- The experimental group consists of 5 teams from the organization who will take the training
program while the control group is formed from the other 5 teams who will not take the training
program.
- To avoid bias by choosing randomly.
E: What would you do with the data you collect to test your hypothesis?
With the collected data, I need to approach the management for the implementation, so that the new
safety training program can be taken by the company as soon as possible.

*Is my answers correct or not? If not tell me the correction ASAP please

Answer 1

A. Hypothesis: The hypothesis I use here is that, If I use a new method where there will be either no injuries or less work-related health issues, health and safety risks to be controlled, then the health and safety is completely guaranteed.

The new method of safety training is significantly more effective than the current method of safety training.

B. The number of injuries of employees on the worksite can be measured to find if the new training method is better. A limitation with this information is that all injuries may not be reported and all nay not necessarily be caused due to a failure to adhere to safety norms.

What to measure:

How effective the new one than the previous one?

Hazard burden should be nil or negligible.

Measuring the reactive monitoring of the new training.

How to plan and implement?

C. The independent variable is the training method and the dependent variable is employee safety.

D. The employees who receive the new training would be in the experimental group whereas those who receive the current training would be in the control group. The participants should be randomly assigned.
