المقارنة بين الأوزان القياسية و الافتراضية في تحليل البيانات النوعية

Abstract EN

The research aims to study and compare the standard weights that are brought in the laboratories by means of devices to measure the additives to the experiment and the hypothetical weights that are assumed by the researcher through experience or prediction of default values.

These weights were applied to a laboratory experiment of cucumber plants Usually the plant does not tolerate the salinity of the soil, so the salinity levels of the plant were taken and it was found that its germination rate was weak.

The plant was exposed to a plant hormone that stimulates growth at laboratory-prepared standard proportions (weights) as follows (z1 = 0 z2 = 0.5 z3 = 1.5) that was classified on the levels of salts and after End of time specified period data was recorded An analysis of the recorded data was carried out using standard weights and significant differences were obtained for the plant before adding the plant hormone and after the addition, which explains the importance of adding the auxin hormone to plants to increase their stimulation and their tolerance to salt concentration and increase their germination.

After that, the chi-square analysis was also applied, and through the results, there were significant differences in plant germination percentages.
