When We Use Estimation to Determine the Value of a Parameter

Multiple Choice

When we use estimation to determine the value of a parameter, we always use random sampling, rather than convenience sampling or judgment sampling, because random sampling:

A) avoids the errors inherent in judgment sampling.
B) avoids the errors inherent in convenience sampling.
C) avoids the errors inherent in voluntary response sampling.
D) eliminates the systematic error or bias that arises in nonrandom sampling.
