Question

When constructing a histogram with non-uniform (unequal) class widths, we must ensure that the areas of the rectangles are proportional to the ___________.

• A. Class width
• B. Class sizes
• C. Class frequencies
• D. Range

Answer 1

The correct option is C Class frequencies

When constructing a histogram with non-uniform (unequal) class widths, we must ensure that the areas of the rectangles are proportional to the class frequencies so that the number of entities for each bar corresponds to the area of bar.
