In most of the studies, a large sample size is anticipated to

  • A.get a low level of precision.
  • B.maximize the sampling error.
  • C.get a high level of precision.
  • D.maximize the standard deviation.

Answer: C

A large sample size is expected to give a high level of precision. As the sample grows, the standard error falls roughly in proportion to one over the square root of the sample size, so estimates are closer to the true value.

A low level of precision is the effect of a small sample. A larger sample does not increase the sampling error, and it does not change the standard deviation of the population. The answer is option C.
