Question

In histogram, if widths of the rectangles are varying, then lengths of rectangles are modified to be proportionate to the __________________ class size

Answer 1

Answer: minimum

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.
we need to make certain modifications in the lengths of the rectangles so that the areas are again proportional to the frequencies. The steps to be followed are as given below:
1. Select a class interval with the minimum class size.
2. The lengths of the rectangles are then modified to be proportionate to the class-size.
