In the context of effect sizes, values of 0.80 and 0.90 are considered large according to Cohen's conventions. Similarly, values of 0.95 and 0.99 are also considered large. The value of 1.96 is often associated with statistical significance in a two-tailed test at the 0.05 level, but in the context of effect size, values above this threshold would also be considered large. Therefore, all the provided alternatives are correct examples of large effect sizes.
