Effect Dimension For every comparison, Cohen's d was computed in order to determine the
extent of the group differences. An indicator of impact size called Cohen's d can be used to
assess how practically significant the results are (Cohen, 1988).
Sodium (Na): d = 0.4 (small to moderate effect)
Calcium (Ca): d = 0.6 (moderate effect)
Magnesium (Mg): d = 0.5 (moderate effect)
Antioxidant Activity: d = 0.55 (moderate effect)
The results indicate that although the differences are statistically significant, the impact sizes
are moderate. This suggests that the findings have some practical consequences, although
they are not very substantial.
Correlation Study The association between the mineral content and antioxidant activity of the
organic and non-organic banana samples was examined using a Pearson correlation
analysis.
Relationship: A moderately positive connection (r = 0.65) was found between magnesium
and antioxidant activity in organic bananas (Halliwell & Gutteridge, 2015).
In non-organic bananas, the link between antioxidant activity and calcium was less strong,
with r = 0.40 (Buchanan et al., 2021).
These correlations indicate that increased magnesium concentrations might boost organic
bananas' antioxidant capacity.
An overview of the statistical results in comparison to non-organic bananas, organic
bananas had much greater concentrations of salt, calcium, and magnesium as well as
stronger antioxidant activity, according to the statistical analysis. The effect sizes were
moderate, but the differences were statistically significant.
