CGM Data Collection & Analysis 3

Question 1

A grounds manager records irrigation run times but not actual water applied. What additional data is needed to calculate water application rates?

Accepted Answer

Precipitation rate of the heads

Answer

Precipitation rate (inches per hour output of sprinkler heads) multiplied by run time gives the actual water application volume.

Question 2

Which type of chart is best for comparing the proportional budget allocation across multiple maintenance categories?

Accepted Answer

Pie chart

Answer

A pie chart visually represents parts of a whole, making it ideal for showing proportional budget allocation across categories.

Question 3

In quality control charting for grounds maintenance, what does a data point falling outside the control limits indicate?

Accepted Answer

A potential special cause requiring investigation

Answer

Points outside control limits signal special-cause variation, meaning something unusual affected the process and warrants investigation.

Question 4

What is the primary purpose of conducting a grounds audit using standardized evaluation forms?

Accepted Answer

To ensure consistent, repeatable data collection across staff and time

Answer

Standardized forms ensure that data is collected consistently regardless of who conducts the audit, enabling reliable comparisons over time.

Question 5

A manager finds that irrigation water usage spiked in July despite stable weather. The first analytical step should be:

Accepted Answer

Cross-reference usage data with maintenance logs and meter readings

Answer

Cross-referencing usage data with maintenance records and meter readings helps identify the root cause before making management decisions.
