The following appeared in the editorial section of a daily newspaper:
“Although forecasts of presidential elections based on opinion polls measure current voter preference, many voters keep changing their minds about whom they prefer until the last few days before the balloting. Some do not even make a final decision until they enter the voting booth. Forecasts based on opinion polls are therefore little better at predicting election outcomes than a random guess would be.” |
这道题 除了关于poll的逻辑错误之外，还有什么别的错误啊？战友们帮帮我啊 呵呵先谢谢了 |
