Wide variation in Bihar exit polls

6 Nov 2015 | By Vijaya

Exit poll results from Bihar showed a wide variation among them.

The variation though cannot be explained statistically, but could be slightly attributed to biases in the survey.

Further sampling a heterogenous society like India, which doesn't have a simple two-party system, doesn't necessarily give the complete picture.

Be that as it may, four out of six exit-polls predicted a victory for "Grand Alliance."
