WebThe width of a confidence interval for a meta-analysis depends on the precision of the individual study estimates and on the number of studies combined. In addition, for random-effects models, precision will decrease with increasing heterogeneity and confidence intervals will widen correspondingly (see Chapter 9, Section 9.5.4 ). WebHow to Calculate Margin of Error: Steps. Step 1: Find the critical value. The critical value is either a t-score or a z-score. If you aren’t sure which score you should be using, see: T-score vs z-score. However, in general, for small sample sizes (under 30) or when you don’t know the population standard deviation, use a t-score. uncheater文件夹是什么
