IS SCIENCE A BONE OR A BANE?

These incandescent light bulbs, though helped the world coming out of darkness but they are constantly destroying the environment.
After a lot of research, scientists came out with one good alternative option to these traditional light bulbs. CFL( compact fluorescent light bulbs) are much more energy efficient and do not have any negative effect on the environment like the traditional bulbs. But in spite of knowing all the benefits of these CFL's, people are still not limiting the use of those harmful traditional bulbs.
We all know that lighting plays a very important part in our lives. Around 15% of the total electricity produced is used to provide sufficient light. And from this 15% a major part is wasted as it is consumed by the inefficient incandescent bulbs. Since, today there is a great usage of lighting fixtures everywhere, the increased use of incandescent bulbs is adding to climatic destruction like global warming.
The major disadvantage of traditional light bulbs is that, they are not at all energy efficient sources and are also effecting the eco system. In addition to that the light produced is too dim. So, these reasons should be sufficient for anyone to limit their usage and help protect the environment as finally we would be the sufferers.
According to a research, an incandescent bulb converts only 5% of the energy consumed into light wasting the rest of it whereas a CFL, can almost produce the same amount of light as the energy consumed so saving up to 80% of energy. So, it is clearly evident that CFL is a far better option than the traditional bulbs.
CFL's apart from being energy efficient sources, live for a...

n this fast changing world, problems in almost all fields of human endeavor have to be solved and resolved on scientific bases. The influence of decisions based on quantitative information has never been more evident than in the present decade especially with the use of modern technology. Indeed, the growing complexities of the activities and functions of the various fields of endeavor have made the use of statistics imperative.
However, one major problem among statisticians, under a given circumstance and budgetary constraints, is the production of reliable data due to built-in biases of the collectors and/or respondents.
In many cases, the main cause of failure in any research undertaking is the wrong choice of method in the collection of data. This is especially true in the case...
