उत्तर
A double bar graph can be used to compare two collections of data.
Explanation:
A double bar graph is a type of bar graph that displays two sets of data side-by-side using two bars for each category. This visual representation makes it easy to compare values across the same categories for the two different datasets. For example, you might use a double bar graph to compare the number of boys and girls in different classes or the sales of two products over several months.
