I am undergraduate students who is struggling on how to do in-vivo studies with my low budget. Therefore, I ask some help of you just in case you know about what sample size formula that i could use for my in-vivo studies' sample size. In my research, I have 3 kinds of sample: a. Meniscus b. Artificial Meniscus c. PLA-PCL-PMMA-Collagen Meniscus
Thank you in advance.
