Careful Consideration of Sample Design Must Be Made to Achieve

question 70

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).
$$\begin{array} { l l l l } \text { Factor } &\text { Effect on } \\&\text { Sample Size }\\\hline\text {1. Population size }\\\text { 2. } \text { Variation in the population } & & \\\text { 3. } \text { Tolerable misstatement } & \\\text { 4. Expected misstatement } & \\\text { 5. Risk of incorrect acceptance } & \\\text { 6. Risk of incorrect rejection } &\end{array}$$

Definitions:

Molar Concentration

The amount of a substance (in moles) present in one liter of solution, commonly expressed as moles per liter (mol/L).

Reaction Proceed

The process by which reactants transform into products through chemical changes, influenced by factors like temperature, concentration, and catalysts.

Concentration Effect

The impact that changing the concentration of reactants has on the rate of a chemical reaction.

Reaction Speed

The rate at which reactants are converted into products in a chemical reaction, influenced by factors like temperature, concentration, and presence of catalysts.
