Author’s Name:_________________________ Institutional Affiliation:____________________________ Whenever a research is carried out a certain situation is made and expressed in possible factors that influence that specific situation. These factors that might change themselves and so affect the situation are called variables. While some research is done all except for one to two of total variables are considered constant so that the effect of that one to two respective variables could be deeply studied assessed and analyzed. While there are a number of variables in each studied system it tends to get difficult to measure all of them using one method or better to be said scale since For example when the test would be carried out the researcher must obtain some values of BP and so when these values are noted down or simply recorded this process is observation.
