Basics of Scientific Research

Preface

The idea to create such a book was born earlier, and I would say much earlier than the date of its publishing. The reason was that I studied as a post-graduate student and was forced to pass examinations one of which touched upon the basis of scientific knowledge and philosophy of science.

Nowadays we live in the up-to-date changeable world and still try to beef up true knowledge about laws of it, not only laws of physics that seem to be discovered and passed hard during long ages from the sir Newton till the physician Einstein, from discovery of a wheel up to the appearance of nuclear reactors… It’s just obvious for the part of our life we solve easy and simultaneously complicated tasks, we are keen on to obtain so-called clear understanding this world where we constantly dwell.

And, first of all, we need for basis of scientific knowledge. Because while knowing and comprehending not only its worship Science, but also its formation, we can bravely go ahead for new discoveries.

The book consists of several parts with their own captions where you can get the most necessary information. The great attention is paid to methods and forms of scientific knowledge.

What is Research?

In the broadest sense of the word, the definition of research includes any gathering data, information and facts for advancement of knowledge.

Science does not use this word in the same way, preferring to restrict it to certain narrowly defined areas. The word ‘review’ is more often used to describe the learning process which is one of the underlying tenets of rigid structures defining scientific research.

Definition of research

When you say that you are undertaking a research study to find answers to a question, you are implying that the process:

1. is being undertaken within a framework of a set of philosophies ( approaches);

2. uses procedures, methods and techniques that have been tested for their validity and reliability;

3. is designed to be unbiased and objective.

Validity means that correct procedures have been applied to find answers to a question. Reliability refers to the quality of a measurement procedure that provides repeatability and accuracy. Unbiased and objective means that you have taken each step in an unbiased manner and drawn each conclusion to the best of your ability and without introducing your own vested interest. (Bias is a deliberate attempt to either conceal or highlight something).

Adherence to the three criteria mentioned above enables the process to be called ‘research’. However, the degree to which these criteria are expected to be fulfilled varies from discipline to discipline and so the meaning of ‘research’ differs from one academic discipline to another. The difference between research and non-research activity is, in the way we find answers: the process must meet certain requirements to be called research. We can identify these requirements by examining some definitions of research. The word research is composed of two syllables, re and search. So re is a prefix meaning again, anew or over again, search is a verb meaning to examine closely and carefully, to test and try, or to probe. Together they form a noun describing a careful, systematic, patient study and investigation in some field of knowledge, undertaken to establish facts or principles. Research is a structured enquiry that utilizes acceptable scientific methodology to solve problems and create new knowledge that is generally applicable. Scientific methods consist of systematic observation, classification and interpretation of data. Although we engage in such process in our daily life, the difference between our casual day– to-day generalisation and the conclusions usually recognized as scientific method lies in the degree of formality, rigorousness, verifiability and general validity of latter.

Characteristics of research

Research is a process of collecting, analyzing and interpreting information to answer questions. But to qualify as research, the process must have certain characteristics: it must, as far as possible, be controlled, rigorous, systematic, valid and verifiable, empirical and critical.

Controlled – in real life there are many factors that affect an outcome. The concept of control implies that, in exploring causality in relation to two variables (factors), you set up your study in a way that minimizes the effects of other factors affecting the relationship. This can be achieved to a large extent in the physical sciences (Cookery, Bakery), as most of research is done in a laboratory. However, in the social sciences (Hospitality and Tourism) it is extremely difficult as research is carried out on issues related to human beings living in society, where such controls are not possible. Therefore in Hospitality and Tourism, as you cannot control external factors, you attempt to quantify their impact.

Rigorous – you must be scrupulous in ensuring that the procedures followed to find answers to questions are relevant, appropriate and justified. Again, the degree of rigor varies markedly between the physical and social sciences and within the social sciences.

Systematic – this implies that the procedure adopted to undertake an investigation follows a certain logical sequence. The different steps cannot be taken in a haphazard way. Some procedures must follow others.

Valid and verifiable – this concept implies that whatever you conclude on the basis of your findings is correct and can be verified by you and others.

Empirical – this means that any conclusion drawn are based upon hard evidence gathered from information collected from real life experiences or observations.

Critical – critical scrutiny of the procedures used and the methods employed is crucial to a research enquiry. The process of investigation must be foolproof and free from drawbacks. The process adopted and the procedures used must be able to withstand the most critical scrutiny.

For a process to be called research, it is imperative that it has the above characteristics.

Types of research

Research can be classified from three perspectives:

1. Application of research study

2. Objectives in undertaking the research

3. Inquiry mode employed

Application:

From the point of view of application, there are two broad categories of research: pure research and applied research.

Pure research involves developing and testing theories and hypotheses that are intellectually challenging to the researcher but may or may not have practical application at the present time or in the future. The knowledge produced through pure research is sought in order to add to the existing body of research methods. Applied research is done to solve specific, practical questions; for policy formulation, administration and understanding of a phenomenon. It can be exploratory, but is usually descriptive. It is almost always done on the basis of basic research. Applied research can be carried out by academic or industrial institutions. Often, an academic institution such as a university will have a specific applied research program funded by an industrial partner interested in that program.
