Data Analytics & Visualization Flashcards

A talent consultant is building a workforce planning model. Which analytical approach best accounts for uncertainty in future hiring needs?

Answer: Scenario planning with multiple probabilistic forecasts

Scenario planning with probabilistic forecasts acknowledges uncertainty and prepares organizations for multiple possible futures rather than a single predicted outcome.

When using a heat map to display employee performance data by department and quarter, what does the color intensity typically represent?

Answer: The magnitude or frequency of the measured variable

In a heat map, color intensity encodes the value of the measured variable — darker or warmer colors typically indicate higher magnitudes.

An organization's talent analytics team reports that diverse teams outperform homogeneous teams by 15% on innovation metrics. What critical information is needed before acting on this finding?

Answer: Whether the relationship holds after controlling for confounding variables like team size and tenure

Without controlling for confounders like team size, tenure, and project complexity, the observed performance difference may be spurious rather than attributable to diversity.

Which principle of effective data storytelling involves structuring insights to move from 'what happened' to 'what should we do'?

Answer: The narrative arc (descriptive → diagnostic → prescriptive)

Effective data storytelling follows a narrative arc from descriptive (what happened) through diagnostic (why) to prescriptive (what to do next).

A company wants to compare its time-to-fill metric against industry peers. What type of data source would provide the most relevant external benchmark?

Answer: Industry compensation surveys and HR benchmarking reports

Industry compensation surveys and HR benchmarking reports provide standardized, comparable external data for setting meaningful performance benchmarks.

What is the risk of 'p-hacking' in people analytics research?

Answer: Running multiple statistical tests until a significant result appears, inflating false positive rates

P-hacking involves testing multiple hypotheses or data subsets until a p < 0.05 result appears, which dramatically increases the chance of a false positive finding.

In a workforce dashboard, a 'drill-down' capability allows users to do what?

Answer: Navigate from a summary metric to the underlying granular data supporting it

Drill-down functionality lets users click on a summary visualization to explore the detailed data underneath, enabling root cause investigation.
