Data collected by us is biased in favor of RJD+, so the gap between the two alliances could be lower than this.

Analysis of Bias in Exit Polls carried out in the last one year

We have taken exit polls of assembly elections in the last 12 months and bias towards NDA/BJP

Axis has a negative bias towards BJP of -6.5%. What this means is, BJP/NDA scores 6.5% more than what Axis Predicts. On the other extreme, Ipsos over predicts BJP/NDA seat forecast by 121%. Both Jan ki Baat and CVoter also have delivered forecasts that favour the BJP but not in line with results. 

Let us now look at the track record of Exit Poll companies in the last few elections in Bihar

Here is a rating of Exit Polling Companies  in the last two assembly elections and Lok Sabh elections (2010, 2014, 2015, 2019) in Bihar
