Analysis Phase
When you run a Delphi study, collecting responses is just the beginning. The real value lies in analyzing the data to uncover actionable insights.
Delphi analysis transforms raw expert opinions into clear evidence about priorities, consensus, and disagreement.
Whether you want to see which scenarios experts endorse, detect hidden biases, or compare subgroups, structured analysis makes it possible.
On this page, you'll find everything you need to master Delphi analysis, including:
Descriptive Analysis
Summarize ratings with median, mean, and variability. Quickly see where most experts stand on each topic.
Identify the most supported ideas by ranking items by their average or median score.
Consensus Measurement
Identify where opinions align — and where they don't. Use metrics like interquartile range (IQR) and convergence rates to measure agreement across rounds.
Spot items with strong consensus or persistent dissent.
Stakeholder Group Analysis
Explore how different groups — such as professions, regions, or experience levels — rate each topic. Filter results to compare expert subgroups side by side.
This helps you build balanced recommendations for diverse stakeholders.
Mann-Whitney U-Test
Go beyond simple averages and test whether two groups rate items statistically differently. The Mann-Whitney U-Test is ideal for Likert data and non-normal distributions.
It shows if observed differences are significant and not due to chance.
Sentiment Analysis
Reveal the emotional and cognitive dimensions behind ratings. Assess levels of optimism, positive or negative affect, and other psychological factors influencing judgments.
This adds depth to your understanding of expert perspectives.
Dissent Analysis
Detect where strong disagreement or bias exists. Identify outliers, desirability bias, or polarization using tools like z-scores and the bimodality coefficient.
This analysis clarifies why consensus may be lacking.
Scenario Analysis
Group and rank scenarios to build strategic foresight. Use techniques such as cross-impact analysis and clustering to see how future developments interconnect.
Scenario analysis helps you design actionable roadmaps based on expert judgment.
Comment Analysis
Analyze qualitative comments to understand the reasoning behind ratings. Use Pro and Contra categorization and peer validation through likes.
Comments explain the "why" behind the numbers.
