Hello, I am recently learning data analysis methods. The concept of “multiple regression” confuses me. There are so many factors that might influence the effects of independent variables on the dependent variable, then how can we determine which ones shall be included and others not?

Indeed it is impossible to rule out every confounding factor in data analysis in social work research. What we need to pay attention to is the most important ones to your interest and control other variables. For example, age and education may affect the DV, but you may treat them as control variables in your analysis if they are not of your interest.

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?
