Sta. D සංඛ්‍යාතිය

Definition:

d statistic (noun): A measure of effect size used in statistical analysis, particularly in the context of meta-analysis and hypothesis testing.

The d statistic represents the standardized mean difference between two groups or conditions, indicating the magnitude of the difference in means relative to the variability within the groups. It is commonly used to assess the practical significance of study findings and to compare the effectiveness of different interventions or treatments. A larger d statistic typically suggests a stronger effect or relationship between variables.
