Sample: the first question, solved
In a stacked-bar graph, which part of each bar shows the total for that group?
📘 Worked solution
✓The full height of the entire bar (top to bottom) represents the total of all its stacked categories combined.
And one from the hard end
Compare a well-made stacked-bar graph (starting at 0, consistent scale) to a misleading version (nonzero axis start, inconsistent scale) of the same data. Explain how the misleading version could distort conclusions.
