Effect size and its statistical significance in published papers as metadata in horticultural sciences for application of meta-analysis
In order to conduct meta-analysis abundance of quality metadata are required. Meta-analysis in horticultural sciences is novel approach and the standard methodology for finding metadata is to conduct the data search from related research papers through available databases. In the course of planned meta-analysis available databases were searched for metadata on hail protection of apple orchards specifically regarding impact of hail nets on fruit characteristics.It is observed that in horticultural literature sometimes the case that effect sizes are reported without clearly specifying estimates of variations, sample sizes and even without reporting p-values of applied statistical tests. This is especially often in the cases when several groups are compared with post-hoc test hence indicating the grouping pattern with letters rather than actual biometrical test results. Such practice is understandable from the perspective of simplification of data presentation and comprehension of research results. However from the perspective of possible summarizing and reviewing the results from the multiple researches especially for application in meta-analysis a full set of average effect sizes, with related variability estimates and tested values with its exact significance are recommended to be included in publications.
