Do you think it would be a good idea to stop using the Chi Square test and the T-test altogether, and use effect size indices instead? Explain.
What will be an ideal response?
As you know, Chi Square is a test of statistical significance. There is currently quite a debate about the use of significance tests in the statistics community. What pretty much
everyone agrees on is that it is not sufficient to rely only on significance levels, as they are determined in part by sample size and therefore are a poor guide of the strength of a
relationship. Therefore we should in all cases calculate an effect size measure as well as a significance test. Some researchers say that, in part because significance tests are so
often misinterpreted as effect size measures, and because of the arbitrary nature of the cut off points, it would be better to not use significance tests at all. Most researchers, however, feel that they still have a useful role to play alongside effect size measures.
