UPND's Charles Kakoma on CPD's presidential opinion poll :
Is the opinion of 1,000 people representative of more than 4,000,000 registered voters? That is a joke and his sampling techniques are questionable and too biased. He has not been to all parts of Zambia. How does he know what the entire voting population is saying?
There are many reasons to question the recent opinion poll but the sample size is not one of them! What he should be asking are things like : what was the question asked? how was it worded? what is the sampling error? how representative was the sample? Was there any selection bias? Have they taken into account the "fear factor"? Zambians who plan to vote for the opposition may be unwilling to disclose their intentions for obvious reasons. This is what Mr Kakoma should be focusing on. Quite clearly UPND are not doing any internal polling otherwise he would have understood the main questions around polling. They are going into this election blind!
