    When you encounter an issue that is already knownand have a description of it, you might began towonder why things are the way they are

    The desire to know WHY to explain is thepurpose of explanatory research.

    For Example, a descriptive researcher may discover that

    10 percent of parents abuse their children, whereas theexplanatory researcher is more interested in learningWHY PARENTS ABUSE THEIR CHILDREN

    Refine a Topic intoResearch Question

    Refine and narrow down a topic sufficiently into a problemof Question

    Although the problem is identified in a broader

    perspective, it needs to be defined specifically in terms ofwhat is to be researched. It is important to define theproblem in a precise manner. A well defined problem givesthe researcher a proper direction for carrying outinvestigation. It also helps in utilizing the resources

    provided for the research effectively.

  • 8/14/2019 kiran nasir

    22/44

    A researcher can focus his efforts on collectingrelevant information, if the problem is defined properly.

    Some research problems such as conducting a survey onthe newspaper reading habits of a given sample of thepopulation can be clearly defined.

    But if a company wants to define a research problemsuch as declining sales, it needs to define the researchproblem further through exploratory research.

    Preparing the Statement ofResearch Objectives

    Formal research statement.As precise as possible.Objectives act as guidelines for various steps inthe research process.

    The objectives of the research must be brief andspecific.

    Once the objectives and research questions

    are identified, a researcher has to develop ahypothesis statement that reflects theseresearch objectives.

  • 8/14/2019 kiran nasir

    24/44

    Developing the hypothesis

    A hypothesis is a statement based on somepresumptions about the existence of arelationship between two or more variables

    that can be tested through empirical data. When a researcher is developing a hypothesis,

    he/she will try to assume an answer for aparticular research question and then test it

    for its validity.

    contd..

  • 8/14/2019 kiran nasir

    25/44

    A hypothesis normally makes the research questionclearer to the researcher. The formulation of ahypothesis allows the researcher to make apresumption or guess and can thus ensure that all

    the relevant aspects of the research are includedin the research design.Example why are the sales of refrigerators are going up in

    winter? In this case the hypothesis could bethe sales of refrigerators are going up during winter

    due to off-season discounts. This makes theresearch question much clearer.

    Developing the hypothesis

    Planning the Research Design

    Planning the research design is a crucial step inthe research design process. A research design

    is the actual frame work of research thatprovides specific details regarding the processto be followed in conducting the research.

    The research is designed based on the

    objectives formulated during the initial phasesof the research.

  • 8/14/2019 kiran nasir

    27/44

    The research design includes all the detailsregarding the research such as

    Where the information should be obtainedfrom The time and budget allotted for conducting

    the research

    Select the appropriate measurementtechniques Sampling process.

    Selecting the Research Method

    After developing an appropriate researchplan, it is important for the researcher toselect a proper research method.

    There are four basic methods of conducting aresearch study.

    Secondary data studies

    SurveysExperimentsObservation

    Surveys

    Preparing the questionnaire.

    Collecting the data through telephone.

    Gathering the data from internet. Collecting the data through the personal

    interview method.

    Using the mailed questionnaire method Advantages and disadvantages

    Experiments

    Conducted for studying cause-and-effect relationships.

    Analyzing the sales targets achieved by

    individual salespersons by manipulating theirmonetary rewards is a typical example ofexperimentation.

    Example . Test marketing conducted by companies to

    test the viability of their new product in themarket is a form of business experimentation.

  • 8/14/2019 kiran nasir

    31/44

    Secondary Data Studies

    Concerned with the analysis of already existing data thatis related to the research topic in question.

    Analyze the future sales of a product.For instance, for the cell phone wave protectorresearch, secondary data regarding thetelecommunications setup, mobile networking, thewaves used for communication for communication inwireless telephony and its effects, may be essentialfor assessing the future sales trends of the cellphone wave protector.

    Observation Techniques

    Respondents are observed without anyinterruption by the observers

    The advantage of this method is that theobservers do not depend on the respondents fortheir responses as they are only observed and arenot asked to participate in the research process.

    Although the observation technique is useful, itcannot be used for studying several other factorssuch as motivation, attitudes and so on.

    Selecting the Sampling

  • 8/14/2019 kiran nasir

    33/44

    Selecting the SamplingProcedure

    Once the researcher selects the research method thatis most appropriate for the research, he needs todevelop a sampling procedure.

    Sampling is a process that uses a small number of itemsor a small portion of a population to draw conclusionsregarding the whole population.

    A sample can be considered as a a subset of a larger setcalled the population.

    A well defined sample has the same characteristics asthe whole population.

    Selecting the Sampling

  • 8/14/2019 kiran nasir

    34/44

    When the research is conducted on such a sample theresults obtained will represent the characteristics ofthe whole population.

    Another important aspect of sampling is to decide onthe size of the sample.

    The bigger the sample size the greater will be itsprecision.

    But for practical reasons, it is not feasible to selectlarge samples.

    A sample can be selected in two ways from a population.through probability sampling(or)

    through non-probability sampling

    Selecting the SamplingProcedure

    Probability Sampling

  • 8/14/2019 kiran nasir

    35/44

    When the subsets of a population are chosen in such away that it ensures a representative cross section bygiving every element in the population a known chance

    of being selected, it is calledprobability sampling.

    When subsets of a population in which little or noattempt is made to ensure a representative cross

    section are chosen, it is callednon probability

    sampling.

    Once a researcher decides on a sample, he needs toobtain data from this sample.

    Probability Sampling& Non Probability Sampling.

    Data Collection

    The researcher collects the data from theunits in this sample. As there are severalresearch techniques, there are a number of

    data collection methods as well. In the survey method the data is collected by

    asking the respondents to fill out a

    questionnaire administered to them. In the observation technique the respondentsare just observed without their directparticipation in the research.

    Data collection done inTwo stages

    Pre-testing Main study

    Pre-testinginvolves collecting the data from a

    small sub sampleTest whether the data collection plan for the mainstudy is appropriate.This help the researchers to minimize any

    potential errors that may crop up during the mainstudy.If the results of a pre-test are not appropriatefor decision making, then the researcher mayconsider altering the research design.

    Evaluating the data

    The most important aspect of data evaluation is toconvert the data collected into a format which willfacilitate the Readers in effective decision making.The reason for analyzing the data is to obtain

    research results and to prepare the research report.Evaluation of data normally starts with editing andcoding the dataEditing is undertaken to verify the data and checkfor any potential errors or for any inconsistencies

    and so on.Another task of editing is to remove any errors thatmay have cropped up during the interview such asrecording the answers under the wrong columns of aquestionnaire and so on.

    The interpretation of the data that has beencollected by using different analytical

    techniques according to the requirements of

    the Study is called analysis.

    Several statistical tools are used for dataanalysis, in order to make the analysis suitable

    for effective decision making.
