Comparing groups

What should I do if I want to compare the means of 3 groups or above? I know T-test is only for two groups.

You could consider conduct the Analysis of variance (ANOVA)

Reference: Kim, H. Y. (2014). Analysis of variance (ANOVA) comparing means of more than two groups. Restorative dentistry & endodontics, 39(1), 74-77.

you may try ANOVA on SPSS which is used to determine whether there are any statistically significant differences between the means of three or more independent (unrelated) groups.

This is the F-test in analysis of variance for testing differences among three or more groups. Within the analysis, one can also choose to test the difference between each pair of groups.

Hi there. I found it is really impressive that telehealth is so powerful, far beyond my imagination!

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?
