We compare the test statistic to a critical value from a chi-square distribution to decide whether it’s big enough to reject the null hypothesis that the two variables are unrelated. To do that, we should calculate the expected frequencies and chi-square, find the critical chi-square value, compare the chi-square value to the critical value, and then decide whether to reject the null hypothesis.

Hi, everyone. I get a question! Different stakeholders may have different expectations for the program evaluation. May I ask how evaluators could deal with such contradictory expectations?

Hello. May I ask a question about how to choose the model for program evaluation? Sometimes I find that it is not enough to adopt only one model. Can I use different models in a program evaluation at the same time?

Hi, we are invited to develop an evaluation program on IFSCs. May I ask why we need to clarify the meaning of evaluation to the program personnel? I thought it was common sense.

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?

I have designed a large-scale survey about the life satisfaction of low-income families in Hong Kong. Is it appropriate to use the electronic survey through mobile phones?
