Difference between sample size and effect size?

What is the difference between sample size and effect size? In medical social service practices, how will we differentiate between sample size and effect size? Thanks!

Sample size is a count the of individual samples or observations in any statistical setting,
Effect size is a simple way of quantifying the difference between two groups that has many advantages over the use of tests of statistical significance alone. Effect size emphasizes the size of the difference rather than confounding this with sample size.

I understand the confusion because the names are so similar ;) but as Yuen Hang explains it, I can see how they are different from each other. Thanks!

Sample size is the size the sample. Effect size is the size of the effect of an input on an outcome. The two sizes are different and never comparable. Effect size does not depend on sample size. A larger sample would not generate a stronger effect.

Following the previous post, suppose we have measured the stress level of hidden youth before the pandemic and conduct the same survey one year later and find out there is a decrease in scores. Can we say that the pandemic reduces hidden youth’s stress levels?

Hi, I am afraid I disagree with a previous post that “the pandemic will worsen hidden youth’s situation.” You see, now everyone is asked to stay at home, and hidden youth no longer face pressure from their parents or society to go out, which might reduce their stress level.

Following the previous post, we have used the snowball sampling method and asked the interviewees to introduce their “hidden” peers who would like to accept the interview. But will it have an issue of generalizability?

The outbreak of coronavirus pandemic and social distancing measures might make “hidden youth” even more isolated from society. Our center’s cyber outreaching team is considering online engaging those youth and look for participants who would like to accept interviews. May I ask which sampling method is the most appropriate?

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?
