Cards in this group · 5
- U8.03.1A star marking significance answers whether a difference is real, not how large that difference is
- U8.03.2Running dozens of comparisons without correction guarantees some will look significant by chance alone
- U8.03.3A p-value of 0.049 and 0.051 mean almost the same thing, yet one gets a star and the other doesn't
- U8.03.4Calling a result significant means little until the chart also says which statistical test produced it
- U8.03.5An effect size with its confidence interval tells readers far more than a bare significance star
