What is Single Factor Analysis(SFA)? I really won't go into scientifically defining the terminology because it can get very complicated as the mathematical tools get varied. So I am going to say in very layman terms, what exactly does SFA mean and how do we carry on the analysis. Factor Analysis is an analysis where you take two different variables like : 1. Dependent Variables(DV) 2. Independent Variable(IV) . Then you vary Independent Variable and check the response on the Dependent Variables. The main objective is to prove or disprove that, the change in IV has effect on DV. Therefore, usually in SFA we go by having a hypothesis, that there is a relationship and may prove it wrong or right during analysis. Example I The concentration of the CO2 ( [Co2]) has an effect on the temperature of Earth[T]. The above statement is the hypothesis. It may sound old, as it is the proven fact. But it wasn't back in 1824. And the interesting fact is that the Global Warming was not

It is the sharing which is the cause of reception.
