The chi-squared test is used to study differences between data sets.. It is only used for frequencies (counts), . never. for measurements.. It is used to compare an experimental result with an expected theoretical outcome.. Fixed Effects. Borenstein et al., 2009, pp. 64-65. Random Effects. Borenstein et al., 2009, p. 72. . Typical Model. In most applications of meta-analysis, we want to infer things about a class of studies, only some of which we are able to observe. The inference we typically want is random-effects..
