A data analyst needs to create a data visualization that aids in the cumulative impact of sequentially introduced values that are positive or negative. Which of the following data visualization…

The correct answer is C. A scatter plot. To visualize the cumulative impact of sequentially introduced positive or negative values, a scatter plot can display the running total against the sequence, effectively showing the overall trend of the impact.

Why each option

To visualize the cumulative impact of sequentially introduced positive or negative values, a scatter plot can display the running total against the sequence, effectively showing the overall trend of the impact.

AA bubble chart

A bubble chart is used to display three dimensions of data (x, y, size) and is not primarily designed for showing cumulative impact over a sequence.

BA waterfall chart

A waterfall chart is specifically designed to show how an initial value is affected by a series of intermediate positive and negative values, leading to a final total, which perfectly illustrates cumulative impact.

CA scatter plotCorrect

A scatter plot can illustrate the cumulative impact by plotting the sequential order of values on the X-axis and the running total (cumulative sum) on the Y-axis. This visualization helps an analyst observe the trend and magnitude of the cumulative impact as each positive or negative value is introduced sequentially.

DA line chart

A line chart is typically used to show trends over a continuous range, often time, and while it could show a cumulative trend, a scatter plot provides discrete points of cumulative impact.
