(i. In constructing a frequency distribution, you should try to have open-ended classes such as "Under $100" and "$1,000 and over". (ii) To convert a frequency distribution to a relative frequency distribution, divide each class frequency by the sum of the class frequencies.
(iii) When constructing a frequency distribution, try to include overlapping stated class limits, such as 100 up to 201, 200 up to 301, and 300 up to 401.
A) (i), (ii) and (iii) are all correct statements.
B) (i) and, (ii) are correct statements but not (iii).
C) (i) and, (iii) are correct statements but not (ii).
D) (ii) is a correct statement but not (i) or (iii).
E) (i), (ii) and (iii) are all false statements.

(ii) is correct because to convert a frequency distribution to a relative frequency distribution, you indeed divide each class frequency by the total of all frequencies. (i) is incorrect because open-ended classes should be avoided if possible to ensure each data point falls into a specific class. (iii) is incorrect because classes in a frequency distribution should not overlap; each data point should belong to one and only one class.
