The polls get it right with help from Sample Answers RDD
Congratulations to ICM for achieving the closest prediction to the outcome of the popular vote in the recent UK election.
It is also notable that on this occasion all of those achieving an average error of less than 2% used the telephone for data collection, based upon RDD sampling and we are proud to say that ICM acquired their sample from Sample Answers Ltd.
