New delhi sources stated that exit polls predict which party could win the elections and releases the result after an hour the polling ends. Meanwhile they are considered more accurate than opinion polls that are conducted before the actual voting begins. Reportedly the polls predicted between 242 to 365 for the BJP led National Democratic Alliance (NDA) and between 77 and 164 for the Congress led United Progressive Alliance (UPA).
Furthermore the exits polls can't be the determining factor as history shows that it has gone wrong. According to praveen Chakravarty, chairperson of the Congress Data Analytics Department, he tweeted that 80% of exit poll seat predictions for all parties in large state elections since 2014 are wrong.
Moreover across the globe too, the exit polls prediction has gone wrong. In the australia election that was held last week, most exit polls got it wrong and similar was the case of US presidential election in 2016 and that of Brexit. Further the common pattern that could be seen in the exit poll prediction was that all of them did not take into account the undercurrent that was brewing in the conservative and ultra-nationalist positions.
