Two sided confidence intervals
WebThese intervals can be interpreted in the same way as other 2-sided intervals, such as those for r, d, or g. An alternative approach to aligning significance tests using CIs and 1-tailed p values that can often be found in the literature is to construct a 2-sided CI at a lower confidence level (e.g., 100(1-2\(\alpha\))% = 100 - 2*5% = 90%.
