Reading a Double Bar Graph Worksheet Download
Every question needs BOTH series. A double bar graph whose questions only ever read one bar is a single bar graph with extra ink, so there is no 'how many did X have' here - the ten questions are the difference within a category, the two combined, which category has the biggest gap, which one is tied, how many categories favour one series, which series is larger overall, the difference and the total across the whole graph. The data is generated so each of those has exactly one answer: exactly one tie, a unique greatest difference, at least one category going each way, and different series totals. Sheets 152 and 153 do the same thing with a single series.
