In a political survey the margin of error varies depending on the candidate, that is, it depends on the geographic distribution of his constituency, so it is necessary that this type of survey be carried out within a confidence interval, value agreed by the client and the research institute .
In political research the standard of the confidence interval is 95%, what does that mean? This means that the candidate has a 95% chance of being within the margin of error and 2.5% of being above it and 2.5% of being below it. For example: suppose that in an election poll a candidate appears with 23%, taking into account the margin of error of 2.5%, he will be between 20.5% and 25.5%.
Because of this margin of error, when announcing the fall or rise of a candidate, it is valuable that successive surveys are carried out, comparing only the current survey with the previous one will give an answer with the possibility of much greater error.
