Abstract

The study aimed to identify the effect size and statistical significance of the test (t)

for asample of the research published in the Journal of Educational and

Psychological Sciences, University of Bahrain. In the period from March 2011 to

June 2013, as well as the correlation between effect size and the strength of the

statistical test. It was used descriptive analytical method. The total sample size (60)

study, used the test (t) in the examination of 60 zero hypothesis. By one

representative for each study hypothesis. Of the most important results that there

are 15% of the study sample may have been the expense of effect size, along with the

low significance of the operation, which amounted to less than 0.2 ratio of 58.33% of

the study sample index. As well as that there are statistically significant differences

in favor of rejection of the null hypothesis (16 to accept the premise 0.44 reject the

hypothesis). Also it found a positive correlationcoefficient of Spearman significant

relationship between effect size and the strength of the statistical test worth (0.607)

at the level (0.01), and reached the interpreter contrast ratio (0.36). In conclusion,

the study proposals and recommendations need to use themost important practical

significance, along with statistical significance in research and studies.
