摘要
引入2χ拟合优度检验对单项选择题中各个选项出现的次数进行分析,并且考虑了考试中选项的数字组合和同一选项连续出现的次数,提出一种做选择题的方法,可以有效地提高选择题的判断准确率.
Introducing Chi-square goodness-of-fit test on the one-choice questions to analyze the number of various options, consider the mumbers' combination of options and the continuous appearance of one same number, propose methods for solving the one-choice questions, thereby effectively to improve the accuracy of the judgement on one-choice questions.
