Is eta square calculating from anova table a type of correlation coefficient? Why or why not?
Eta- squared is the equivalent of R-squared. Specially, if you used a set of dummy variables in a regression, the R-sq would be the same as the Eta-sq from an ANOVA.
Merhaba Mutlu Umaroglu bey,
Eta -kare ya da etki büyüklüğü bir korelasyon katsayısı değildir. Hipotez testlerinde istatistiksel olarak anlamlı olan değerlere ait pratikteki anlamlılığı verir. Genellikle düşük orta ve geniş etki olarak yorumlanır. Anlamlılık düzeyi ne kadar sıfıra yakınsa o kadar geniş bir etkiye sahiptir.

Hakan Koğar could you please formulate your answers in english, so that all of us can learn from your possibly valuable answers?!
Rainer Duesing Here is my answer's translation:
Eta-square or effect size is not a correlation coefficient. It gives the practical significance of values that are statistically significant in hypothesis tests. It is generally interpreted as low, medium and large effect. The closer the significance level is to zero, the broader the effect.
