Panel sampling - sampling decisions, Operation Research

Panel Sampling

Here the initial  samples are down  on random  basis  and information  from  these is collected  on regular  basis. Itis  semi permanent sample where members may  be included  repetitively  for successive  studies. Here  there  is a facility  to select and quickly  contact  such well  balanced samples and to  have relatively  high  response  rate even by mail.

Advantages of Panel Sampling

a.Lesser  cost  and time  involved  in the  collection of information.

b.Due to fixed  sample units  one can  measure the changes  in repeated reporting.

c.Shifts of behaviour over time can  be traced.

Disadvantages of Panel Sampling

a.The sample may not  fully  representative.

b. The members  of the  panel  may becomes conditioned to some  specific  situations.

c. It may  be difficult to preserve  the representative character of the panel  for a long time  as the  professional  members  of the  panel  may drop out  voluntarily and may  need  replacement.
