Solution

is it possible for a study with a very small effect size to be statistically significant?

Yes, when the sample size is very large, even for the small effect size to be statistically significant.

(Larger samples increase the chance of finding a significant difference).

Is it possible for a study with a very large effective size to yield results that are not satistically significant? Explain

Yes, when the sample size is very small, even for the large effect size are not statistically significant
