Some netizens have taken to social media to voice their concerns over a comment made by media personality Nana Aba Anamoah regarding election polls conducted by Global InfoAnalytics.
In a social media post shared on X on 18 November 2024, Nana Aba questioned the credibility of the polls, suggesting that they did not meet the required standards.
“Musah Danquah’s personal confidence in his polls is fine, but when the sample size is a fraction of the electorate, it’s worth questioning a lot, including the methodology.
“Assuming the minimum sample size is what you’re using now, how do you have so much confidence that an analysis of 2,600 people can truly determine the outcome of a decision to be taken by (using the previous election results) over 6 million people?
“It’s not about calculator and margins of error. It’s about a representative sample size. Your latest poll used 2,623 people. I’m not questioning statistical analysis & accuracy, but how can you tell me that figure is representative?” she said.
Meanwhile, the founder of Global InfoAnalytics, Mussa K. Dankwah, has responded to the questions raised by the media personality.
“It is not difficult to calculate a sample size required for a given population; it is available free on the internet. But let me help you here: for a voting population size of 18.7 million, if you want to conduct a poll in this population with a confidence level of 95% and a margin of error of 1.9%, the minimum sample you need to interview is 2,600, roughly.
“Please take your calculator and try this next time you criticise anyone’s sample size,” he said.
Some netizens have also raised concerns on social media, suggesting that Nana Aba is questioning the credibility of the polls because they did not favour the New Patriotic Party (NPP).
