Sample size bias in the estimation of means.
The present research concerns the hypothesis that intuitive estimates of the arithmetic mean of a sample of numbers tend to increase as a function of the sample size; that is, they reflect a systematic sample size bias. A similar bias has been observed when people judge the average member of a group of people on an inferred quantity (e.g., a disease risk; see Price, 2001; Price, Smith, & Lench,...
متن کاملSample size estimation in epidemiologic studies
This review basically provided a conceptual framework for sample size calculation in epidemiologic studies with various designs and outcomes. The formula requirement of sample size was drawn based on statistical principles for both descriptive and comparative studies. The required sample size was estimated and presented graphically with different effect sizes and power of statistical test at 95...

متن کاملThe Effect of Sample Size and Cognitive Strategy on Probability Estimation Bias
Probability estimation is an essential cognitive function in perception, motor control, and decision making. Many studies have shown that when making decisions in a stochastic operant conditioning task, people and animals behave as if they underestimate the probability of rare events. It is commonly assumed that this behavior is a natural consequence of estimating a probability from a small s...
متن کاملSample Size Calculation for Comparing Means
Sample size calculation plays an important role in clinical research. In clinical research, a sufficient number of patients is necessary to ensure the validity and the success of an intended trial. From a statistical point of view, if a clinically meaningful difference between a study treatment and a control truly exists, such a difference can always be detected with an arbitrary power as long ...
