could anyone pls list some advantages (merit) of replicating procedures/studies in psychological research as i cant find info about this anywhere in my textbook or the internet as you may all know it is a newly added study design dot point that textbooks never cover. and what would be the effects of sample size in obtaining reliable data.

Advantages of replicating studies:
• reaffirms results are valid and reliable
• ability to generalise to different populations (e.g. different ages, ethnicities etc.)
• can help to determine previous extraneous variables and control them
Effects of sample size:
• greater sample size means greater ability to generalise and therefore more reliable data
• smaller sample size means less of an ability to truly generalise and therefore less reliable data
Hope this helps!

There’s not much in my textbook either so I’m assuming (double check with your teacher when school starts) that this is what the study design is talking about.thanks for replying. its very annoying how textbooks dont cover all the dot points/areas in the study design but anyways thx for the help
