No, they are two different things.
Random sampling is a type of probability sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected.
Random assignment is a way of placing participants into treatment and control groups using randomization. With random assignment, every member has a known or equal chance of being placed in a control or treatment group. Random assignment helps you ensure that all groups are comparable at the beginning: any differences between them are due to the treatment rather than sampling or selection bias.

Building on the previous post, can you provide any insight on whether a bar graph would be an appropriate method to represent the educational attainment of parents?

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?
