Waterfall Charts are also known as Bridges and are used to present which of the following?

• A. Variance analysis
• B. Trend lines
• C. Population distribution
• D. Cumulative sums

Answer: (A)

Waterfall charts show how an initial value is adjusted by a sequence of positive and negative changes to arrive at a final value. This makes it easy to see how each factor contributes to the overall difference between planned and actual results, which is exactly what variance analysis aims to reveal. Trend lines track changes over time without breaking down the components; population distribution focuses on data spread; while cumulative sums show totals built up over steps without emphasizing the individual contributors. So the best fit is variance analysis.
