When the graph is analyzed, it can be seen that all of the effect sizes are at a positive
and significant level. While the lowest effect size is 0.245, the greatest effect size
was calculated as 1.099.

When Graph 2 is analyzed, it can be seen that all effect sizes are at a positive and
significant level. While the lowest effect size is 0.354, the greatest effect size was
calculated as 0.935.
Analysis of Effect Sizes based on the Relationship between School Effectiveness
and Leadership and School Climate according to Moderator Variables
For the effect sizes calculated based on the relationship between school effectiveness
and leadership, moderator analysis was carried out according to the school level and the
location the study was carried out in. The analyses results are shown in the table below.
