Is the procedure likely to yield a representative sample or a biased sample? Explain why. O A. The procedure is likely to yield a representative sample because the subjects are all chosen to be similar as part of the design of the experiment. Therefore, any sampling method will yield patients which are identical in all the aspects relevant to the study. O B. The procedure is likely to yield a biased sample because the researcher knows the patients from treating them previously and that will influence her decision as to which patient will get an increased dosage. O C. The procedure is likely to yield a biased sample because the subgroup size of 32 is too small. O D. The procedure is likely to yield a representative sample because there is no bias in the selection process
