MUMBAI: In a series of interrelated opinion and exit polls over the next two months NDTV will be conducting among the biggest and most rigorous polling exercises ever - covering over 350 (out of the 543) Lok Sabha constituencies with a total sample size of over 2 lakh. The sample selection methodology is based on electoral rolls to ensure a random sample with other technology innovations and new methods of interviewing voters (for example, wherever feasible, women field-workers interviewed female voters).

 
Witness the biggest election coverage in the history of Indian television as NDTV presents the most credible, non-partisan, non-sensational election analysis.

The channel will also undertake a separate re-contact exercise through phone calls just before the elections to gauge shift of voters’ opinion over time. More than 350 constituencies will be covered across the opinion polls and the Exit Poll will also cover more than 350 constituencies. These opinion polls will be conducted in three phases which will seek to understand the mood of the nation and electoral preferences for parties; get a pulse of the nation and analyse shifts in voter perception and preference followed by an Exit Poll for seat prediction state-by-state.

NDTV will be using innovative methods to ensure  better data quality which will include regular updates and tracking through mobile telephonic-surveys, votes to seats conversion based on proprietary IPR using homogenous swing zones, multi-party swings and margins of victory and changes in the extent of vote-splitting in each homogeneous swing zone.

Fieldwork and interviews conducted by Hansa Research Group. Watch Prannoy Roy and Dorab Sopariwala present India's BIGGEST EVER Opinion Poll on Thursday 13 and Friday 14 March from 8-10pm
