Which of the following are the characteristics of a •good sample' in research?
A. Readily accessible
B. Representative of population characteristics
C. Serving the personal considerations of the researcher
D. Precision and accuracy in approximating the parameters
E. Freedom from bias
Answer and explanation
Correct answer B
A good sample represents the population, estimates its parameters with precision and accuracy, and minimizes bias: B, D and E only. Ready accessibility does not establish representativeness, and serving the researcher’s personal considerations undermines sound selection. The other combinations include these unsuitable criteria or omit the required ones.
