The best method the writer should use is to randomly select 100 people who voted in the last election. This approach ensures that every voter has an equal chance of being included in the sample, which helps minimize bias and enhances the representativeness of the data. In turn, this leads to a more accurate estimation of the mean age of all voters, providing valuable insights for the article. Additionally, it’s essential to keep in mind that randomness in sampling is like the secret sauce in a good recipe – it makes all the difference! Common mistakes in sampling include selecting only from one demographic, which can skew results. By ensuring a truly random selection, the writer can flavor her findings with a well-rounded perspective on the voting population's mean age.
