Compare two different groups that differ in size?

I would like to compare two different parental groups on the percentage of different employment rate. Since the groups are in differnt size, how can we deal with in programme evaluation? Thanks!

I think this issue comes up often when we try to compare certain variable between two groups... Thanks Dr MEL!

Usually, the size difference is not an issue. The concern is about the use of a nonparametric statistical test, such as the Kruskal-Wallis test to test the unemployment rate, which unlikely displays a normal distribution. Nevertheless, one reasoning logic of any is that the sample parental distribution resembles the population parental distribution. That is, when the unequal numbers of parental groups are realistic in the population, it is logical for the test.

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?
