“…There have been numerous research studies regarding the PhD degrees. These studies have discussed various topics such as interest of students in pursuing PhD degrees (Ayoola, Kamp, Adams, Granner, DeGroot, Lee, & Doornbos, 2021), undergraduate GPA and PhD (Mendoza-Sanchez, DE Gruyter, Savage, & Polymenis, 2022), employability of local and international PhD students (Tani, 2022), success factor of PhD students (Young, VanWye, Schafer, Robertson & Poore, 2019;Van Roil, Fokkens-Bruinsma, & Jansen, 2021).
