Title: Sources of Data
Post by: Badshah Mamun on April 28, 2012, 12:07:47 PM

Sources of Primary Data

The sources of generating primary data are -

Observation Method
Survey Method
Experimental Method

Experimental Method

There are number of experimental designs that are used in carrying out and experiment. However, Market researchers have used 4 experimental designs most frequently. These are -

CRD - Completely Randomized Design

RBD - Randomized Block Design -
The term Randomized Block Design has originated from agricultural research. In this design several treatments of variables are applied to different blocks of land to ascertain their effect on the yield of the crop. Blocks are formed in such a manner that each block contains as many plots as a number of treatments so that one plot from each is selected at random for each treatment. The production of each plot is measured after the treatment is given. These data are then interpreted and inferences are drawn by using the analysis of Variance Technique so as to know the effect of various treatments like different dozes of fertilizers, different types of irrigation etc.

LSD - Latin Square Design -
A Latin square is one of the experimental designs which has a balanced two way classification scheme say for example - 4 X 4 arrangement. In this scheme each letter from A to D occurs only once in each row and also only once in each column. The balance arrangement, it may be noted that, will not get disturbed if any row gets changed with the other.
A    B    C    D
B    C    D    A
C    D    A    B
D    A    B    C
The balance arrangement achieved in a Latin Square is its main strength. In this design, the comparisons among treatments, will be free from both differences between rows and columns. Thus the magnitude of error will be smaller than any other design.

FD - Factorial Designs -
This design allows the experimenter to test two or more variables simultaneously. It also measures interaction effects of the variables and analyzes the impacts of each of the variables.

In a true experiment, randomization is essential so that the experimenter can infer cause and effect without any bias.

Sources of Secondary Data

While primary data can be collected through questionnaires, depth interview, focus group interviews, case studies, experimentation and observation; The secondary data can be obtained through

Internal Sources - These are within the organization
External Sources - These are outside the organization

Internal Sources of Data

If available, internal secondary data may be obtained with less time, effort and money than the external secondary data. In addition, they may also be more pertinent to the situation at hand since they are from within the organization. The internal sources include

Accounting resources
- This gives so much information which can be used by the marketing researcher. They give information about internal factors.
Sales Force Report- It gives information about the sale of a product. The information provided is of outside the organization.
Internal Experts- These are people who are heading the various departments. They can give an idea of how a particular thing is working
Miscellaneous Reports- These are what information you are getting from operational reports.

If the data available within the organization are unsuitable or inadequate, the marketer should extend the search to external secondary data sources.

External Sources of Data

External Sources are sources which are outside the company in a larger environment. Collection of external data is more difficult because the data have much greater variety and the sources are much more numerous.

External data can be divided into following classes.

Government Publications-
Government sources provide an extremely rich pool of data for the researchers. In addition, many of these data are available free of cost on internet websites. There are number of government agencies generating data. These are:

Various Associations of Press Media.
Export Promotion Council.
Confederation of Indian Industries ( CII )
Small Industries Development Board of India

The only disadvantage of the above sources is that the data may be biased. They are likely to colour their negative points.
Syndicate Services- These services are provided by certain organizations which collect and tabulate the marketing information on a regular basis for a number of clients who are the subscribers to these services. So the services are designed in such a way that the information suits the subscriber.
