Use an accent wall to define a living space. Accent colours are great for creating a defined area in a multi-functional space (think open-concept loft or studio apartment). Paint a little nook to create a home office or an inset wall to define your sleeping space like in the image above.
Every true experimental design must have this statement at the core of its structure, as the ultimate aim of any experiment. The hypothesis is generated via a number of means, but is usually the result of a process of inductive reasoning where observations lead to the formation of a theory.
In research, a hypothesis is a suggested explanation of a phenomenon. A null hypothesis is a hypothesis which a researcher tries to disprove. Normally, the null hypothesis represents the current view/explanation of an aspect of the world that the researcher wants to challenge.
