In psychological research, there is something called correlational study which is used very frequently. In simple terms, correlational study defines the relationship between two variables; these variables could be anything – like for example – your health and your performance, or your personal life and your public life or success and your self-esteem.
The possible outcomes of correlational studies are:
1. Positive – When increase of one variable causes the other variable to increase.
2. Negative – When increase of one variable causes the other variable to decrease
3. No correlation – When change in one variable doesn’t cause any change in the other variable.
Our life is wound around correlational objects. Changes in one thing can cause negative or positive affects in various other things. For example if you had a fight with your family at home, it is most likely to cause you to have a bad temper at work. You might end up hurting someone at work which in turn can cause that person to shout at his family at home. So indirectly your family at home is positively correlated to your colleague’s family. This is just a hypothetical scenario; it might not always be true.
The point here is, we must treat every variable in our life separately – each variable must have no correlation to the other. You should never let changes in one thing affect something else. Doing so will only cause an imbalance in your life. Every aspect of your life should be treated and worked on independently. It will not only make your life simpler but will also make you more efficient and balanced at what you do.
