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!

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.

Following the previous question, I wonder if we could find more evaluative results for supporting telehealth expansion during the COVID-19 crisis.

Hi there. I found it is really impressive that telehealth is so powerful, far beyond my imagination! It turns out telehealth covers so many themes, including the telehealth modalities (e.g., video, asynchronous), clinical topics (e.g., chronic disease management), telehealth function (e.g., remote patient monitoring, consultations). Could you help me with its effectiveness? It seems impossible for me to summarize.

Hi there. While it sounds like data visualizations are so valuable, I wonder if there is any weakness about it that social workers should keep in mind?

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?
