In a histogram with unequal widths, a class of width 20 has frequency 30, while all other classes have width 10. To keep areas comparable, the adjusted bar height for this class should be:

Question

Accepted Answer

15. Adjusted height = frequency x (standard width / actual width) = 30 × 10/20 = 15.

In a histogram with unequal widths, a class of width 20 has frequency 30, while all other classes have width 10.
To keep areas comparable, the adjusted bar height for this class should be:
