WebUSMLE Epidemiology and Biostatistics Meta-Analysis: pools data from several studies (greater power), limited by quality/bias of individual studies Clinical Trial: compares two groups in which one variable is manipulated and its effects measured Cohort (relative risk): compares group with risk factor to a group without – asks “what will happen?” (prospective). WebJan 18, 2024 · With samples, we use n – 1 in the formula because using n would give us a biased estimate that consistently underestimates variability. The sample variance would tend to be lower than the real variance of the population. Reducing the sample n to n – 1 makes the variance artificially large, giving you an unbiased estimate of variability: it is better to …
