Question #: 119
Topic #: 5

An operations manager wants to measure variability in the delivery time of insurance policies to clients. Which of the following quality tools most appropriately would show the level of variability?

APareto chart

BHistogram

CScatterplot

DCheck sheet

Show Suggested Answer

Suggested Answer: B

A histogram is the most appropriate quality tool to measure variability in the delivery time of insurance policies to clients because:

Distribution Visualization: A histogram displays the distribution of data points, showing how delivery times are spread out. This helps in understanding the range and frequency of delivery times.

Identifying Variability: It allows for easy visualization of the level of variability or dispersion in the delivery times, highlighting any inconsistencies or outliers in the process.

Data Analysis: Histograms provide a clear picture of the central tendency, spread, and shape of the data distribution, which is crucial for identifying patterns and potential areas for improvement.

Decision Making: By showing the distribution of delivery times, a histogram helps the operations manager make informed decisions about process adjustments to reduce variability and improve consistency.

A Pareto chart (Option A) is used to prioritize problems based on their frequency or impact. A scatterplot (Option C) shows relationships between two variables, not the distribution of one. A check sheet (Option D) is used for data collection and not for showing variability in data.

Check sheets are useful, but not for measuring variability directly.

True, but for just variability, histogram is simpler.

Pareto chart? Nah, that's for analyzing the most common problems, not variability in delivery times.

I'm with Keena on this one. Scatterplot is way off the mark. Histogram is the way to go.

Haha, a check sheet? What is this, the 1950s? We need some real data visualization here, not just a simple tally.

Scatterplot? Really? That would show the relationship between two variables, not just the variability in one.

I could be wrong, but I think a check sheet is more for data collection rather than analyzing variability. I lean towards the histogram.

I feel like a Pareto chart is more about identifying major issues rather than measuring variability, so I don't think that's it.

I'm not entirely sure, but I remember practicing with scatterplots for showing relationships between variables. Not sure if that applies here.
