මහින්ද දිනනවලු. හැබයි සමික්ෂණයක් කරේ නෑලු.
Prof. Peiris, who is the President, Institute of Applied Statistics Sri Lanka (IASSL), Vice President of Organisation of Professional Associations (OPA) and Head of the Department of Mathematics, University of Moratuwa says that the expected valid votes in January 2015 will be 1,080,338.
Following is an interview with Prof. Sarath Peiris.
Q: Did you carry out a survey to find the people's opinion?
A: No. By my experience (මොකෙන්ද දන්නෙ නෑ) in applied statistics I do not recommend to conduct a survey to find the people's opinion on Presidential candidates as selecting a representative sample is not an easy task due to lack of unbiased sampling frame.
