NEW DELHI: Exit polls for the Bihar Assembly elections are set to be released after the second and final phase of the “mother of all polls” concludes on Tuesday. All eyes will be on whether the Nitish Kumar-led National Democratic Alliance (NDA) will be able to retain power or if the Mahagathbandhan will emerge victorious.Ahead of the results, scheduled for November 14, exit polls will offer an early glimpse of how Bihar voted. However, exit polls are not always accurate — in fact, the past two predictions by psephologists and political analysts for Bihar Assembly polls were not just off the mark but far from reality.The Assembly elections were held in two phases — on November 6 and November 11. In the first phase, half of Bihar went to the polls, recording a historic turnout of 65.08%. The Election Commission of India has directed agencies not to publish any exit poll data until the second phase of voting concludes completely.What are exit polls?Exit polls are surveys conducted by questioning voters immediately after they cast their ballots. They differ from opinion polls, as they are based on how people have actually voted rather than their future intentions.Exit polls provide an early indication of voter preferences. Since it is not possible to survey every voter, trained teams ensure the sample represents voters from diverse backgrounds.2020 assembly polls predictionThe Times Now–C-Voter exit poll for the 2020 Bihar Assembly elections had predicted a hung assembly, projecting 116 seats for the NDA and 120 for the Mahagathbandhan (Grand Alliance).
