Sentence examples for classification of effects from inspiring English sources
We have also observed cases where the allele effects split into multiple classes or where the classification of effects into discrete clusters is not clear.
However, in practice, the prenatal developmental toxicity study (OECD test guideline 414; OECD 2001a) is needed to apply the criteria for developmental toxicity, and the two-generation reproduction toxicity study (OECD test guideline 416; OECD 2001b) is needed for classification of effects on fertility (Ohlsson A, Swedish Chemicals Agency, personal communication).
Cohen [ 63] proposed a threefold classification of effect sizes: small (0.20 - 0.49), medium (0.50 - 0.79), and large (0.80 and above).
Using Cohen's classification of effect sizes, 31 effect size was small for smoking behaviour and attitudes, while there was a medium effect on smoking-related knowledge.
Additionally, the classification of effect sizes (f) was determined by calculating partial η 2 p. According to Cohen [ 27], 0.00 ≤ f ≤ 0.24 indicate small effects, 0.25 ≤ f ≤ 0.39 indicate medium effects, and f ≥ 0.4 indicate large effects.
To allow comparison with reported intervention effects from previous reviews, including interventions in the general adult population, effect sizes were described according to Cohen's classification of effect size small (0.2 to <0.3), medium (0.3 to <0.8 and large (>0.8).
Therefore, instead of using significance criterion, we used Cohen's classification of effect sizes for interpretation and focused only on correlations of 0.5 or higher which are considered strong [ 23].
The classification of effect size (ES) was determined by calculating partial η p 2. According to Cohen [ 22] ES can be classified as small (0.00 ≤ ES ≤ 0.24), medium (0.25 ≤ ES ≤ 0.39), and large (ES ≥ 0.40).
Cohen's d allows classification of effect size into small (0.2 to 0.5), medium (0.5 to 0.8) and large (0.8 or over); these criteria can also be applied to SMR [ 49, 50].
