Determining Sample Size Page 2 - Tarleton

Determining Sample Size Page 4 Suppose our evaluation of farmers’ adoption of the new practice only affected 2,000 farmers. The sample size that would now be necessary is shown in Equation 4. As you can see, this adjustment (called the finite population correction) can substantially reduce the necessary sample size for small populations.

Using Margin of Error to calculate sample size

p If we use σ=3.5, then the sample size we should choose is n=(1.96×3.5/0.25)2 = 753 p However, suppose the true standard deviation turns out to be σ=4.5. p The MoEusing a sample size 753 turns out to be p 0.32 is larger than the desired 0.25! p MoralUse n = 1537 to be sure the MoEis less than 0.25.

Statistics: An introduction to sample size calculations

3 Power-based sample size calculations We have seen above that precision-based sample size calculations relate to estimation. Power-based sample size calculations, on the other hand, relate to hypothesis testing. In this handout, the formulae for power-based sample size calculations will not be derived, just presented.

Sampling and sample size estimation

n: the desired sample size z: the standard normal deviate usually set at 1.96 (which corresponds to the 95% confidence level) p: the proportion in the target population to have a specific characteristic. If no estimate available set at 50% (or 0.50) q:1-p d: absolute precision or accuracy, normally set at 0.05. Sample Size Calculation

Sample Size Calculations Using SAS, R, and nQuery Software

The sample size for a study is typically calculated based on the primary hypothesis of interest. Because of this, secondary and exploratory analyses may be underpowered and should not be used to make claims but can influence design of future studies. This is an

Experimental design and sample size determination

Reducing sample size •Reduce the number of treatment groups being compared. •Find a more precise measurement (e.g., average time to effect rather than proportion sick). •Decrease the variability in the measurements. –Make subjects more homogeneous. –Use stratification. –Control for other variables (e.g., weight).
