Lift overloading
Scenario: The Elevator Experiment
Background:
In the bustling metropolis of Statistopolis, the city engineers are concerned about the safety of elevator usage in skyscrapers. To address this, they've developed a cognitive activator applet to simulate elevator loads and understand the risk of overloading.
Objective:
As a junior data scientist at the Department of Urban Infrastructure, you're tasked with using this applet to conduct an experiment that will help determine safety thresholds for elevator usage.
Investigation Steps:
1. Setting Parameters:
- Choose a mean weight per passenger and a standard deviation that reflects the diverse population of Statistopolis.
- Set the maximum lift load for the elevators in the city's skyscrapers.
2. Running Simulations:
- Use the applet to generate thousands of trials, simulating daily elevator usage.
- Observe and record the number of cases where the elevator load exceeds the safety threshold.
3. Analyzing Results:
- Calculate the percentage of trials that result in an overload.
- Discuss the implications of this percentage for public safety.
4. Making Recommendations:
- Based on your findings, recommend a course of action for the city engineers.
- Consider whether to advise changes in elevator capacity, reinforcement of current lifts, or public awareness campaigns about elevator usage.
Questions for Investigation:
1. Discovery Question:
- How does changing the mean weight or standard deviation affect the overload rate?
2. Real-world Implications:
- What real-world factors could lead to an increase in the average weight of passengers over time?
3. Policy Decisions:
- If the overload rate is above an acceptable level, what policies could be implemented to mitigate the risk?
4. Reflection:
- Reflect on how this simulation helps in making data-driven decisions for urban planning and infrastructure.
