CFA Practice Question
When a researcher uses the classes 129-147, 147-165, and 165-183 to create a distribution, he is violating which of the following suggested practices?
B. Avoid the use of uneven or non-standard classes
C. Avoid the use of overlapping classes
A. Avoid the use of open-ended classes
B. Avoid the use of uneven or non-standard classes
C. Avoid the use of overlapping classes
Correct Answer: C
The classes are overlapping (e.g., the classes "147-165" and "165-183" have the point "165" in common). There are no open-ended classes and the classes have the same class interval.
