A research analyze is basically a work of measuring a set number of variables and conditions with which the desired phenomena is discover and quantified (Krysik Finn , 2007 . Data analysis can only translate and hap meaning to the gathered data and it cannot lay claim to separate findings or generalizations if the data does not support it . And , in to extrapolate the most accurate answer to the research questions , the method with which data was gathered should also be accurate and above scrutiny .
