What tp match the EVs on ? I put age but gender works too i think
•
How is the validity affected by the researcher knowing which participants are in which group and how to fix this? = investigator effect and to fix double-blind or change the researcher for that step.

strength of using matched pairs instead of repeated measures = participants matched on a variable thats relevant to study so high validity

Sign test s value = 3

Design = had to include aim, IV, DV, CVs, EV = noise ? and how to prevent, I said bar chart with separate keys because discrete data ... i wasn't sure.
