In disguise observations the observer has the best opportunity to observe the participants, the observer get true and unbiased results.
The observer should observe the situation without any biases or personal interests. In natural sciences observation can be conducted along with the other methods that the researcher is using. Observation alone cannot suffice in natural sciences. Interviews are another important method of primary data collection. Interviews are expensive as compared to other methods of data collection. In the interview the interviewer collects information from each respondent independently.
Due to this reason it becomes costly as well as time consuming. Interview as a research tool can only be used if the researcher has plenty of time and resources, otherwise it will be wastage of time and money to start interviewing.
Interviews are more reliable as compared to observation. This facilitates in depth knowledge of the situation, phenomena or individual.
The most important limitation of interview is the time that is required to conduct it properly. To obtain reliable results interview should be conducted by a single interviewer rather than having many.
Sometimes the interviewees live in distant areas, reaching each respondent becomes difficult. The interview is basically conducted in social science studies.
In the interview the interviewer can make an inventory of questions before starting the interview, in another case the interviewer asks questions spontaneously. Spontaneous questions are better if the purpose of the interview is to find out in depth knowledge. The interviewer may ask spontaneous questions when he has little knowledge of the subject areas. The interviewer records the responses during the interview or at the end of the interview.
To conduct an interview the interviewer should have command of social skills and he should develop a rapport with the audience in order to get genuine responses. The questionnaire is one of the most commonly used methods of data collection in research. Questionnaires are formulated to get to the point information on any subject area. The questionnaire is an inexpensive method of data collection as compared to other methods of primary research.
Questionnaires can be submitted by the vast audience at a time and the responses can be obtained easily. The only drawback of questionnaire is the low feedback as several people do not return questionnaires on time. Several respondents do not show true responses in questionnaires.
In the interview the interviewer can observe the gestures of the respondents but in questionnaires the respondents do not know whether the answers are genuinely true or not.
To formulate a questionnaire the researcher should formulate questions that do not contain double meaning. Questions should have to be written in easy language that anyone can understand. Questions should have to be simple and not very technical. The researcher should follow the ethics of writing and the language of the questions should not be humiliating. Experiments are the most reliable source of data collection in natural sciences.
Experiments can be conducted in any area of scientific study, whether it is chemistry, biology, physiology, physics, astronomy or mathematics. In this type of research, the researcher uses information gathered by government agencies, associations, labour unions media sources and so on. The data assembled is primarily published in newsletters, magazines, pamphlets, newspapers, journals, reports, encyclopaedias etc.
You can find out the difference between primary and secondary research, in the following points in detail:. Both primary and secondary research have their advantages and disadvantages. While primary data is need-specific and quality is also up to the mark, but it is expensive and consumes more time. Secondary research, on the other hand, is cheap, and the data collection is easy, but it is also possible that the data may be outdated and does not suit your requirements.
So, before choosing any of these two, first examine your requirements, sources, costs, etc. Your email address will not be published.

Key Differences Between Primary and Secondary Research You can find out the difference between primary and secondary research, in the following points in detail: Research conducted to gather first-hand information, for the current problem is called Primary Research.
Secondary Research is one that involves the use of information obtained originally by primary research. Primary Research is based on raw data, whereas secondary research is based on analysed and interpreted information. The primary research, the data is collected by the researcher himself or by the person hired by him. As against this, the secondary research, the data collection is performed by someone else.
The primary research process is very involved which deeply explores the topic. Conversely, the secondary research process is fast and easy, which aims at gaining broad understanding about the subject. In primary research, as the researcher conducts the research, the data collected is always specific to the needs of the researcher.
As opposed to secondary research, wherein the data lacks particularity, i. Primary research is an expensive process; wherein high cost is involved in the exploration of data and facts from various sources.
Unlike Secondary research, is an economical process wherein the low cost is involved in acquiring pertinent information because the data is already collected by someone else. Primary research consumes a lot of time as the research is done from scratch.

Primary research usually costs more and often takes longer to conduct than secondary research, but it gives conclusive results. Secondary research is a type of research that has already been compiled, gathered, organized and published by others.
Primary market research is the most common type of a market research method and is also the most valuable type. It is a method that only answers specific questions and not irrelevant issues. Secondary market r esearch. Secondary research is defined as an analysis and interpretation of primary research. The method of writing secondary research is to collect primary research that is relevant to a writing topic and interpret what the primary research found.
Primary data increases the reliability and authenticity of research and in most of the scientific researches primary data are used. Primary methods of data collection There are different types of primary data and they are used according to the type of study. Primary research is a time-tested method, therefore, one can rely on the results that are obtained from conducting this type of research. Disadvantages of Primary Research One of the major disadvantages of primary research is, it .
