    • A Presentation on Research In Management By Satakshi Kaushik BBA Sem iv
    • Index 1) Meaning of research design 2) Features of a good research design 3) Exploratory research design 4) Descriptive research design 5) Diagnostic research design 6) Hypothesis-testing research design
    • Meaning of research design A research design is one that minimizes bias and maximizes the reliability of the data. It also yields maximum information, gives minimum experimental error, and provides different aspects of a single problem. A research design depends on the purpose and nature of the research problem. Thus, one single design cannot be used to solve all types of research problem, i.e., a particular design is suitable for a particular problem.
    • Features of a good research design The means of obtaining information  The availability and skills of the researcher and his staff, if any; The objective of the problem to be studied; The nature of the problem; and  The availability of time and money for the research work. It should be flexible enough to consider different aspects of the study in case of exploratory. The design should be accurate with minimum bias in case of accurate description
    • design It is a type of research conducted for a problem,but the problem itself has not been clearly understood. In other words, exploratory research is a process of gathering facts and doing research that later allows for the team to create the best research design or data collection method available for specific subjects. This process will draw definitive conclusions only with caution due to the nature of the process. In many cases, this process leads to the understanding that no problem actually exists. Exploratory research is guided by a set of hypotheses 1) Operational definition 2) Statistical testing
    • design Descriptive research design is a type of research method that is used when one wants to get information on the current status of a person or an object. It is used to describe what is in existence in respect to conditions or variables that are found in a given situation. The Office of Human Research Protections defines a descriptive study as “Any study that is not truly experimental.” Descriptive studies can involve a one-time interaction with groups of people or a study might follow individuals over time
    • design Diagnostic research studies determine the frequency of occurrence of something or its association with something else. From the research design point of view, the design of such studies should be rigid and should focus on the following: 1) Objective of the study (what the study is about and why is it 2) 3) 4) 5) 6) being made?) Methods of data collection (what techniques of data collection will be adopted?) Sample selection (how much material will be needed?) Data collection (where the required data can be found and with what time frequency should the data be related?) Data processing and analysis Reporting the findings
    • Hypothesis-testing research design Hypothesis-testing research studies, also known as experimental studies, an experiment is a study in which a treatment, procedure, or program is intentionally introduced and a result or outcome is observed. The American Heritage Dictionary of the English Language defines an experiment as “A test under controlled conditions that is made to demonstrate a known truth, to examine the validity of a hypothesis, or to determine the efficacy of something previously untried.” True experiments have four elements: 1) 2) 3) 4) manipulation control random assignment and random selection. The most important of these elements are manipulation and control. Manipulation means that something is purposefully changed by the researcher in the environment. Control is used to prevent outside factors from influencing the study outcome
