Change Management Research & Evidence-Based Practice 4 — Questions and Answers
Question 1: Which statistical technique is most appropriate for identifying distinct employee clusters with similar attitudes toward a change initiative?
- Linear regression
- Cluster analysis (Correct answer)
- ANOVA
- Factor analysis
Correct answer: Cluster analysis
Cluster analysis groups individuals into subsets based on similarity across multiple variables, revealing distinct audience segments.
Question 2: When applying evidence-based change management, 'stakeholder values and concerns' are considered because:
- They are the sole basis for decision-making
- Local context and stakeholder perspectives are essential evidence alongside research findings (Correct answer)
- They override scientific evidence in all cases
- Regulatory requirements mandate stakeholder input
Correct answer: Local context and stakeholder perspectives are essential evidence alongside research findings
Evidence-based practice integrates research evidence with stakeholder values and organizational context for well-rounded decisions.
Question 3: A researcher reports p < 0.001 for a change intervention study but the effect size is d = 0.08. A practitioner should interpret this as:
- Highly meaningful—the p-value confirms the finding's importance
- Statistically significant but practically negligible (Correct answer)
- Insufficient evidence to draw any conclusion
- Proof that the intervention caused the outcome
Correct answer: Statistically significant but practically negligible
A very small effect size (d = 0.08) indicates minimal practical impact even if the result is statistically significant due to large sample size.
Question 4: Which approach best exemplifies 'continuous improvement' using research in organizational change?
- Conducting a single pre-change survey and acting on results
- Establishing ongoing feedback loops that regularly collect and apply data throughout the change lifecycle (Correct answer)
- Hiring external consultants to evaluate change outcomes annually
- Benchmarking against industry competitors at project completion
Correct answer: Establishing ongoing feedback loops that regularly collect and apply data throughout the change lifecycle
Continuous improvement requires iterative data collection and application throughout the change process, not just at one point in time.
Question 5: When a systematic review on change management is described as 'narrative,' this typically means:
- It only includes qualitative studies
- Studies are summarized descriptively without quantitative pooling of results (Correct answer)
- It focuses on storytelling methods within organizations
- All included studies must use interview-based methods
Correct answer: Studies are summarized descriptively without quantitative pooling of results
A narrative systematic review synthesizes findings descriptively when study heterogeneity or data limitations prevent statistical meta-analysis.
Question 6: A change manager wants to measure whether a leadership training program caused improvements in team performance. The strongest approach would be to:
- Survey team members about perceived leadership quality after training
- Compare team performance metrics before and after training using a control group (Correct answer)
- Interview senior executives about their observations
- Benchmark the organization against industry standards post-training
Correct answer: Compare team performance metrics before and after training using a control group
Pre-post measurement with a control group isolates the training's effect from other factors influencing team performance.
Question 7: The 'file drawer problem' in change management research refers to:
- Poor document management during change initiatives
- The tendency for negative or null results to go unpublished, skewing the available evidence base (Correct answer)
- Withholding change plans from employees until implementation
- Legal risks of storing sensitive employee research data
Correct answer: The tendency for negative or null results to go unpublished, skewing the available evidence base
Publication bias toward positive results means interventions may appear more effective than they actually are when negative findings are suppressed.
