Answer #1

Ans . The diminutive stature and small brain of Homo floresiensis may have resulted from island dwarfism - an evolutionary process that results from long term isolation on a small island with limited food resources and a lack of predators.

Homo floresiensis is a small species of archaic human which inhabited the island of Flores, Indonesia, until the arrival of modern humans about 50,000 years ago.

The small body size of Homo floresiensis may have helped the species survive on an island with limited resources.

In the realm of quantitative measure research, there are those researchers who believe some small violations of the homogeneity of variance assumption may have little practical effect on the analysis due to the robust nature of parametric tests. However, other researchers believe any violation of the homogeneity of variance assumption can result in tarnished or unbelievable results regardless of the robust nature of parametric tests. Discuss the viability or falsity of both viewpoints and how you would approach one view...
