Which of the following is TRUE about probability sampling methods?
A)In most cases,the raw size of the sample is less important than the fraction of the population that the sample represents.
B)A smaller sample tends to be more representative of a population than a larger drawn from the same population.
C)A sample of 3% of the population is always more representative of the population than a sample of 2% of the population,regardless of the size of the sample drawn.
D)The more heterogeneous a population is,the more likely a sample will be representative of it.

Probability sampling methods aim to represent the population accurately. The raw size of the sample is not as important as the fraction of the population it represents. A smaller sample can still be representative if it is chosen using a correct probability sampling method. The important aspect is that the sample is chosen correctly and has a good representation of the population. Therefore, option A is the correct choice. Option B is incorrect because a larger sample generally gives a better representation of the population than a smaller one. Option C is incorrect because a larger sample size will generally be more representative of the population than a smaller sample size. Option D is incorrect because a more homogeneous population is more likely to be representative of the sample.
