Both approaches have their place in research. Both have their strengths and weaknesses. In many studies you have to combine both qualitative and quantitative approaches. For example, suppose you have to find the types of cuisine/accommodation available in a city and the extent of their popularity. Types of cuisine is the qualitative aspect of the study as finding out about them entails description of culture and cuisine. The extent of their popularity is the quantitative aspect as it involves estimating the number of people who visit a restaurant serving such cuisine and calculating the other indicators that reflect the extent of popularity [2, 3, 4].

Science

Here are some common definitions of science:

– Branch of knowledge or study dealing with a body of facts or truths systematically arranged and showing the operation of general laws, e.g., the mathematical science;

– Systemic knowledge of the physical or material world gained through observations and experimentation;

– Systematized knowledge in general;

– Any of the branches of natural or physical sciences;

– A particular branch of knowledge;

– Knowledge, as of facts or principles; knowledge gained by systematic study;

– Skill, esp. reflecting a precise application of facts or principle; proficiency.

The word Science comes from Latin word "scientia" meaning "knowledge" and in the broadest sense it is any systematic knowledge-base or prescriptive practice being capable of resulting in prediction. This is why science is termed as highly skilled technique or practice. However, in more contemporary terms, science is a system of acquiring knowledge based on scientific process or method in order to organize body of knowledge gained through research. Science remains a continuing effort on the part of human being to discover and increase knowledge through research. Scientists can make observations, record measureable data related to their observations, analyze the information in hand in order to construct theoretical explanations of phenomenon involved.

Man's respect for knowledge is one of his most peculiar characteristics. Science came to be the name of the most respectable kind of knowledge. But what distinguishes knowledge from superstition, ideology or pseudoscience? The Catholic Church excommunicated Copernicans, the Communist Party persecuted Mendelians on the ground that their doctrines were pseudoscientific. The demarcation between science and pseudoscience is not merely a problem of armchair philosophy: it is of vital social and political relevance. Many philosophers have tried to solve the problem of demarcation in the following terms: a statement constitutes knowledge if many people believe it sufficiently strongly. But the history of thought shows us that many people were totally committed to absurd beliefs. If the strength of beliefs were a hallmark of knowledge, we should have to rank some tales about demons, angels, devils, and of heaven and hell as knowledge. Scientists, on the other hand, are very skeptical even of their best theories. Newton's is the most powerful theory science has yet produced, but Newton himself never believed that bodies attract each other at a distance. So no degree of commitment to beliefs makes them knowledge. Indeed, the hallmark of scientific behaviour is a certain skepticism even towards one's most cherished theories. Blind commitment to a theory is not an intellectual virtue: it is an intellectual crime. Thus a statement may be pseudoscientific even if it is eminently 'plausible' and everybody believes in it, and it may be scientifically valuable even if it is unbelievable and nobody believes in it. A theory may even be of supreme scientific value even if no one understands it, let alone believes it [5].
