  77. Answer :

    It is very important question that from where we get these data. Internal sources data are its own data and whereas far external source data are to be collected, how this data is to be collected, using which technique, this is what we will study in detail here. As you already know data is of two types:

    1. Primary
    2. Secondary.
    Secondary data has already been collected and Primary data are to be collected by the investigator himself. This data is collected according to its objective using certain methods.

    Direct personal investigation:-

    In this method investigator goes in person to person contact in the area which he wants to execute the investigation and collect the information and data. To collect right data or information through this method the investigator has to be hard working, unbiased, able, and full of patience. For example to know about the living standard of a particular area the investigator has to collect the data by coming directly in contact with the people of that particular area. Then this method would be called as direct personal investigation method.This method cannot be used everywhere. This method is most suitable for those conditions:

    1. Where field of investigation is restricted.
    2. Where confidentiality data is important.
    3. Where data is to be collected directly from the peoples.
    4. Data required in original form.
    This method could be used only if this is useful, suitable and effective. Main features of this method are :

    1. *Data collected through this method are dependable because investigator collects them themselves.
    2. Data collected in original.
    3. Data collected is homogeneous and uniform as collected by single hand.
    4. As data collected directly from the respondents so level of accuracy is high.
    5. This method is elastic in nature so changes as per need could be effected by the investigator.
    6. Data can be collected to vast nature by this method.
    Where there are so much advantages of this method it has got few demerits also these are:

    1. This method requires large amount of money, time and hard work.
    2. Suitable for limited area of investigation not suitable for large area.
    3. As data collected by a person personally so chance of biasing is high.
    4. Method can be used only by able, wise, and patience investigator, not by ordinary investigator.
    5. Method not suitable for large number of respondents.
  78. Discuss the Indirect oral investigation method along with its merits and demerits.
  79. Answer :

    Some investigations are of such/nature that respondents do not wish to provide the directly such as the investigations for the collection of data regarding the habit of sigarette smoking in the student and alcohol taking habits; students doesn’t wish to give any data openly or directly. In these situations we use indirect oral investigation method. In this method we don’t contact the respondents directly but collect the data from the person associated with the respondents. For example in case of data regarding cigarette and alcohol we will not directly ask the students but we will ask for the data from the teashop near the college canteen, etc. Success of this method depends upon the calibre, knowledge, daring nature, and behaviour of the person asking for the data. We should also have the knowledge under which circumstance this method is suitable. Indirect oral investigation is suitable under these circumstances:

    1. Where direct contact with respondents is not possible.
    2. Where field investigation is very vast.
    3. Where data to be collected is of typical nature and could be collected only by the experts.
    4. Where respondents could not provide information due to unawareness.
    This method normally used by the committees either government or private.

    Merits of this method are as follows :

    1. Method is simple and less time taking.
    2. Area of investigation, wide open.
    3. Method is less costly.
    4. Method is un-biased.
    5. By this method we can know the opinion of the experts.
    Where there are merits of the method, we also have following demerits of the method.

    1. Information can be of biased nature in this method also.
    2. Informations could be wrong because information are not in original form.
    3. Respondents could behave carelessly because the information being asked is not directly related to them but with another side.
