A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group. For example, a classroom of 30 students with 15 male and 15 female students could generate a representative sample that might include six students: three males and three females.

Someone told me that a pretest is a more important component of a quasi-experimental design. Could you please elaborate more for me, taking the older adult group as an example?

There are many dropout cases in my samples of older adults living in the community. I wonder can I use the pretest score to examine differences among the remaining group members?

If our team plans to conduct a longitudinal study to examine the impacts of a program for older adults, may I ask the function of its pretest?

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?
