Title: biology ia2 student experiment
Post by: tclare on April 28, 2021, 08:14:59 pm

Hi, I'm hoping to get feedback on my ia2 student experiment about the relationship between bird diversity and the disturbance of locations.

I haven't finished my rationale or risk assessment, but I'm mainly wanting feedback on my evaluation part since I'm still not confident on the difference between reliability and validity.

Thanks

Hi!

Welcome to the forums; please find attached feedback :)

Note that validity is about the question "Am I truly measuring the impact of the IV on the DV?" whereas reliability is asking "Could these same or very similar results be obtained again?"

I hope this helps!
