Hi, I am currently preparing for a survey in which I aim to categorize study participants into 3 groups and collect their contact emails. (To provide some context, participants who have completed the baseline survey will be randomly assigned to one of the three groups). My goal is to recruit a total of 75 participants, ensuring that each group consists of 25 individuals. Once the groups are created, each will receive a separate survey via email.
How can I accomplish this?
Thanks in advance!
