Lyric Lyric is a loosely defined term for a broad category of non-narrative, non-dramatic poetry, which was originally sung or recited with a musical instrument, called a lyre [see voice, sound]. Generally, lyric poets rely on personal experience, close relationships, and description of feelings as their material.t is perhaps no coincidence that a contemporary definition of lyric is the words of a popular song (OED), since in both poetry and music the words are illogically connected for sound not meaning. Drama has likewise had to redefine itself so that theatricality remains its essence (Fried; see objecthood).
Youâve heard it a million times, the idea is that if you have an estimate of .003 (on some reasonable scale in which 1 is a meaningful effect size) and a standard error of .001 then, yes, the estimate is statistically significant but itâs not practically significant.
Effect size is a simple way of quantifying the difference between two groups that has many advantages over the use of tests of statistical significance alone. Effect size emphasises the size of the difference rather than confounding this with sample size. However, primary reports rarely mention effect sizes and few textbooks, research methods courses or computer packages address the concept. This paper provides an explication of what an effect size is, how it is calculated and how it can be interpreted. The relationship between effect size and statistical significance is discussed and the use of confidence intervals for the latter outlined.
