Careful Consideration of Sample Design Must Be Made to Achieve

Essay

Careful consideration of sample design must be made to achieve efficient and effective statistical samples. This is accomplished through explicit specification of key factors and relating them through mathematical models. Consideration of the same factors in nonstatistical samples may help to produce more efficient and effective samples, even if the factors are not explicitly quantified.
REQUIRED: For each of the factors listed below, indicate its effect on sample size by inserting a D (for direct) or an I (for inverse) in the appropriate column(s).
$$\begin{array} { l l l l } \text { Factor } &\text { Effect on } \\&\text { Sample Size }\\\hline\text {1. Population size }\\\text { 2. } \text { Variation in the population } & & \\\text { 3. } \text { Tolerable misstatement } & \\\text { 4. Expected misstatement } & \\\text { 5. Risk of incorrect acceptance } & \\\text { 6. Risk of incorrect rejection } &\end{array}$$
