Question 1

When analyzing fleet maintenance data to identify trends, which statistical measure best describes the typical repair cost per vehicle?

Accepted Answer

Mean

Answer

The mean (average) repair cost per vehicle is the most common measure used to describe typical costs in fleet maintenance analysis.

Question 2

A fleet manager wants to determine whether a new preventive maintenance schedule reduces breakdowns. What type of study design best supports this causal conclusion?

Accepted Answer

Controlled before-and-after comparison

Answer

A controlled before-and-after comparison allows the fleet manager to attribute changes in breakdowns directly to the new maintenance schedule.

Question 3

In evidence-based fleet management, 'benchmarking' primarily involves:

Accepted Answer

Comparing your fleet's performance metrics against industry standards or peer organizations

Answer

Benchmarking compares a fleet's key performance indicators to industry standards or similar organizations to identify gaps and opportunities.

Question 4

Which data source would provide the most reliable evidence for evaluating long-term vehicle reliability?

Accepted Answer

Fleet management system historical records

Answer

Fleet management system historical records contain objective, longitudinal data on actual vehicle performance and maintenance history.

Question 5

A technician reviews three separate studies on brake pad longevity, each reaching different conclusions. The best evidence-based approach is to:

Accepted Answer

Conduct a meta-analysis or systematic review of all three studies

Answer

A systematic review or meta-analysis synthesizes findings from multiple studies to reach a more reliable overall conclusion.
