How we did it
THE WEEK/CNN-IBN/CSDS pre-poll survey interviewed 4,198 people across Karnataka, between April 10 and 17. The 75 constituencies in the study were picked using the Probability Proportionate to Size method. Four polling stations within each sampled constituency and the respondents (from the latest electoral rolls) were selected using the Systematic Random Sampling technique.
* The survey was conducted about a week before the release of the final list of candidates and the start of campaigning.
* The seat projection was compiled by Dr Rajeeva Karandikar, director, Chennai Mathematical Institute.
