The Friedman test is applied to problems with the following characteristics:
A) the problem objective is to compare two or more populations
B) the data are either ordinal or interval but not nominal
C) the data are generated from a randomized block experiment
D) all of these
E) the problem objective is to compare two or more populations and the data are either ordinal or interval but not nominal
Friedman Test
A statistical examination, free from parametric limits, designed to detect treatment variations across a series of tests.
Randomized Block Experiment
An experimental design that groups subjects into blocks based on a characteristic to reduce variability, then randomly assigns treatments within blocks.
Ordinal
Pertaining to a type of data or scale that expresses order or ranking among categories without implying precise measurements.
- Identify the attributes and necessary conditions to employ the Friedman test.
- Determine the correct statistical strategies for the examination of ordinal or interval data obtained from randomized block experiments.

Final Answer :
D
Explanation :
The Friedman test is applied to problems where the objective is to compare two or more populations, the data are either ordinal or interval but not nominal, and the data are generated from a randomized block experiment. Therefore, the correct choice is D, which includes all of these characteristics.
